75 or 90 for planted?
 
Hello All -

First Id like to say, THANK YOU - You've all been so helpful the last few
days.
Ive decided to go with a bigger tank then the 29 that i currently own.

Id like a 75 or 90 from all-glass. Which of these is better for the planted
aquarium in yoru optinion, and where is the best tank for my buck? any mail
orders, or something to that effect?

Thanks In Advance!

Dustin

Ordinarily, bigger is better, but for a planted tank, I'd go with the 75
gallon.
The 90 and the 75 have the same "footprint." The only difference is the 75 is
21" high, and the 90 is just over 25" high. A planted tank deeper than 24" can
be difficult. That depth is hard to light adequately. (You wouldn't think
only a few inches would make a difference, but it does, because light intensity
falls exponentially with distance.)

A planted tank also requires constant maintenance, and if the tank is that
deep, it will be difficult (unless you have really long arms!). I've heard of
people who accidentally poisoned all their fish, because they reached into a
deep tank without showering first, and their underarm deodorant got into the
tank.

As for price...mail order for a tank this size is not economical. The shipping
will kill you. Your best bet is probably to order it from a chain like PetCo.
The big chains use tanks as "loss leaders," selling them at a loss in hopes
that they'll make it up by selling you fish, accessories, etc. Call around
your LFSs and ask, but IME, the small local shops will all charge hundreds of
dollars more than the big chains. The local shops around here all wanted $700
to $800 for an All-Glass 75 gallon economy tank and stand. PetCo asked $325
for tank, stand, and glass canopy top.

I have a 135 gallon tank that is 24 inches high. Leigh, as usual, gives
excellent adivce. She (I hope you are a she Leigh-- if not then I
appologise in advance..) is right about the light, though I find that even
though its tougher to light the bottom of the tank, 25 inches is not
insurmoutable-- especially if you are going to terrace. In addition, I
personally think that less than 24 inches looks a little funny with a
canopy. You may (or may not) choose to place a canopy over the top of the
tank-- but assess how you think it may look with the shallower tank in the
event you do want a canopy. Keep in mind also that there may be plants that
you want to keep that get tall. It may be nice to have certain sections of
the tank that are deeper than others. Just keep in mind that you may have
trouble with high light plants in the deep areas.

Certainly the "long arms" issue is real also. If you are a small person,
then you may want to avoid buying a tank that is too deep for you to reach
into. I know my wife would have a hard time reaching the bottom of my 135
gallon tank. I do not have a problem with this depth-- though any deeper
would become a hassel.

In summay, my cutoff would be about 24 inches-- not 21 inches. 25 inches
may be problematic, but its worthy of careful consideration.

For what its worth, that is my 2 cents. -Bruce Geist

Thanks for the input you two :)

I bought a 125 gallon today on sale at the lfs, I got a better discount
since I am friends with the manager, 599.00 Im guessing that is a good
price :)

Any suggestions for lighting this for plant growth? :)
Thanks!

Sounds like a reasonable price to me. If you are into DIY, then it's
possible to build your own stand and canopy and save a few bucks.

I've never attempted to build a big tank because of the bracing - as far as
I'm concerned, if I spend a hundred bucks on a tank, what I'm really paying
for is that molded plastic frame.

Does anyone have a link to a good DIY plan for a big tank?

I bought a 125 gallon today on sale at the lfs,

Congratulations! A 125 is a nice size for plants, IMO. Six feet long, 18"
wide, just under 2 feet deep. With this size, you can use just about any
lighting you want. Though, price-wise, flourescent tubes might make the most
sense.

Are you getting a compressed CO2 system for the tank, too? If not, it's
probably best to keep your lighting levels down at around 2 wpg. 125 gallon is
sort of large for DIY!

The stand and hood make it a little less ugly. I thought you were talking
just about the tank. I still prefer the DIY method though... Come
January, I'll get to set up 3x100g tanks w/ rack system for nothing more
than time. :) Oh, and I'll have to buy some silicon. And a couple of
valves probably. But it's not going to cost me thousands like it would if
I bought it from a store :)

the tank that are deeper than others. Just keep in mind that you

may
have trouble with high light plants in the deep areas.

Certainly the "long arms" issue is real also. If you are a small
person, then you may want to avoid buying a tank that is too deep

for
you to reach into. I know my wife would have a hard time reaching
the bottom of my 135 gallon tank. I do not have a problem with

this
depth-- though any deeper would become a hassel.

In summay, my cutoff would be about 24 inches-- not 21 inches. 25
inches may be problematic, but its worthy of careful consideration.

For what its worth, that is my 2 cents. -Bruce Geist

Ordinarily, bigger is better, but for a planted tank, I'd go with
the 75 gallon.
The 90 and the 75 have the same "footprint." The only difference
is the
75 is
21" high, and the 90 is just over 25" high. A planted tank

deeper
than
24" can
be difficult. That depth is hard to light adequately. (You
wouldn't
think
only a few inches would make a difference, but it does, because
light
intensity
falls exponentially with distance.)

A planted tank also requires constant maintenance, and if the

tank
is
that
deep, it will be difficult (unless you have really long arms!).
I've
heard of
people who accidentally poisoned all their fish, because they
reached
into
a
deep tank without showering first, and their underarm deodorant

got
into
the
tank.

As for price...mail order for a tank this size is not economical.
The
shipping
will kill you. Your best bet is probably to order it from a

chain
like
PetCo.
The big chains use tanks as "loss leaders," selling them at a

loss
in
hopes
that they'll make it up by selling you fish, accessories, etc.
Call
around
your LFSs and ask, but IME, the small local shops will all charge
hundreds
of
dollars more than the big chains. The local shops around here

all
wanted
$700
to $800 for an All-Glass 75 gallon economy tank and stand. PetCo
asked
$325
for tank, stand, and glass canopy top.

I agree, a lot of the cost is the plastic, but they also use thicker
glass than you really need to, as the plastic doesn't add enough
strength. As I said in another post, I'll be making some big tanks in a
couple of weeks here. They'll be 3/8" glass with angle iron frames, and I
plan on fully photo-documenting the whole process. I'll post a link here
later if you like.

I've never attempted to build a big tank because of the bracing - as

really paying for is that molded plastic frame.

Does anyone have a link to a good DIY plan for a big tank?

I would go with AH Supply kits. The 96 watt kits would fit just
fine on this tank. Say four kits for 384 watts, that would give you
over three watts per gallon, and that is a HUGE amount of light for a
large tank. Many large tanks only run about two watts per gallon.

You do anything -- metal halide, flourescent, PCF.

3 wpg is a lot of light for a tank this size -- more than it would be for a
smaller tank. Many people find 2 wpg is more than enough for a tank over 100
gallons. Make sure your CO2 system is up and running before you turn all that
light on!

PCFs from AH Supply would work well and be pretty easy, but if it were my tank,
I think I'd go with regular flourescent lights. It would be cheaper, and you'd
have more flexibility that way. If you wanted to start out with less light
until you get more experience, you could, just by leaving a few tubes out. If
you need to reduce the lighting for some reason (going to be away from the tank
on vacation, say), you could. You could create sunrise and sunset effects, by
putting different tubes on different timers. You could replace a few tubes
with "moonlight" bulbs, and be able to watch your tank at night. Etc.

I have seven 55 watt CF lamps over my 135 gallon, which is just a bit
taller than the standard 125 gallon size, but which shares the same
footprint. I have two all-glass fixtures that are 36 inches long, and
another three AH supply style kit lamps that are each 24 inches in length.
The All-glass fixtures, which I like a lot by the way, have two lamps per
fixture.

I was able to get by with 220 watts -- the two All-glass fixtures alone--
for the first year. I found that I needed more light as the tank grew, as
they say, shade happens! I think I have about the right amount of light
currently. I assume four 96 watt lamps would do well for you in your tank.
You may wish to use only two or three of them initially, two lamps down
the center of the tank or two lamps towards the rear and 1 lamp as a second
row in front centered with respect to the rear two lamps. As plants grow in,
you could then put in all four. If you put one lamp in the front, centered
on the tank, you may want to put square dowels down on either side of it to
elevate the lamp cabinet slightly off the glass (that I assume you will
have), since it may teeter otherwise. The other lamps will probably match
up with the standard plastic supports supplied on most tanks.

Eventually, my guess is you will want all four 96 watt lamps-- though you
may be able to get by with less. I did for a year.

Congratulations on your new purchase. (I wish I had time for another couple

You need to have a balance: light, fertilizer, CO2. Increase one, and you must
increase the others, too, or plants won't grow well and algae will take over
(because of the extra light & nutrients the plants aren't using).

In addition, a high-light tank without CO2 injection can suffer large daily
swings in pH, as the plants strip the CO2 they need out of the water during the
day, then release CO2 back into the water at night.

Did you get the needle valve? Adding a needle valve makes it a "low-pressure"
system. I think that's what most of us who use compress CO2 use.

You always have to watch out for "CO2 dump" when the tank gets empty. When you
see the pressure gauge starting to drop, it's time for a refill. Don't try to
save a penny or two by getting every last molecule of CO2 out of the cylinder.
If you don't have time, turn off the CO2 at the tank valve. Better no CO2 for
a little while than a CO2 dump.

As for the price...yes, if money is an issue, you can rustle up your own system
for cheaper. But a lot of people find compressed gas very intimidating. They
don't know what to get, or how to hook it up. It's worth it, for many people,
to pay a little extra to get a complete system, along with directions for
putting it together and "tech support" if you have problems.

$100 if you are really good at shopping around and looking for
bargins. $150 if not.

A decent CO2 regulator can be found at almost ANY time on ebay for
$30-40.

Here's one (I don't know the seller, just giving an example) on ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll...m=3102858 289

This is the EXACT same regulator I'm using, and the one Dave Gomberg
sells (or at least sold me) for $75 or so...

A CO2 tank should cost you no more than $50.00 or so from your local
gas supplier or welding supply store.

A needle valve can be purchased new for $20.00. I got mine from
Marine Monsters, but I've heard they are having some trouble. If this
is still the case, I know I've seen several other places selling
needle valves for about the same price. I know Robert over at
Aquabotanic sells one for $18.00

A reactor can be made cheap using a small powerhead and a gravel vac
tube.

The product is perfectly fine. The problem is that the system doesn't
use a needle valve.

But even without a needle valve, the system is SAFE, and works fine.
The issue is what is known as an "end of tank dump". Co2 regulators
are intended to operate with a tank pressure of 800-2000 psi (CO2
pressure will never get that high, it's usually around 800-1000psi).
On the regulator, the high pressure gauge is marked in red from
0-600psi. This is because, when the CO2 runs out, the tank pressure
drops down. The regulator is unable to properly regulate when the
tank pressure is very low. In theory, anything below 600psi is a
problem. In practice, I've run my regulator (from Dave Gomberg) down
to 300-400psi with no "dump". But in any case, once the pressure
drops below the regulators minimum, the regulator looses the ability
to regulate the output properly, and the output pressure will rise.

Since with the "high pressure system" the pressure directly controls
the bubble rate, this rising output pressure results in a CO2
overdose.

At the extreme end, the regulator can completely loose control when
the tank pressure drops very far. At that point, it would vent all
the remaining CO2 in a sudden burst.

For all of these cases, simply adding a needle valve will provide a
safety net.

But, if you keep an eye on the tank pressure, it's easy to notice
BEFORE the tank pressure drops very far. Unlike watching your car's
gas gauge, the CO2 pressure will remain constant (around 800-1000psi
depending on the temp) until the tank is 99% empty. When the CO2 tank
is filled, the CO2 is under pressure, and is in a liquid form. As
long as ANY liquid CO2 remains in the tank, the pressure stays at that
800-1000psi. Once all the liquid is gone, the pressure will start to
drop.

On my tank, with a fairly high CO2 flow rate, I would get about a week
from the time the pressure first started to drop, till it reached the
600psi mark. So even without a needle-valve, if you glance at the
CO2 pressure once every few days, you will see it in time to prevent a
problem.

On my system, with a needle-valve, I intentionally let the pressure
drop all the way down. I run the regulator pressure at about 6psi
normally, and then control the bubble rate with the needle-valve. I
usually have a bubble rate around 2-3 bubble per second. As the tank
pressure dropped below 300psi, the output pressure rose up slowly to
about 15-20psi. I never saw a true "end of tank dump" with a big
spike in output pressure. And the bubble rate (because of the needle
valve) didn't increase much, less than 1 extra bubble per second.

Possibly a bigger issue with the Dave Gomberg high pressure system, if
it's the same as when I bought mine several years ago, is that the
tiny little Eheim diffusor isn't very effective in large tanks. In my
75g, I was unable to get acceptable CO2 levels using it. I ditched
the eheim diffusor, added a needle-valve, and built my DIY reactor,
and I've been very happy ever since.

I've been using DIY on my smaller tanks and just using the big one as a
nursery because I couldn't bear the though of a) figuring out how to hook

up
and maintain seven or eight soda bottles, or b) spending real money.


$100 if you are really good at shopping around and looking for
bargins. $150 if not.

A decent CO2 regulator can be found at almost ANY time on ebay for
$30-40.

Here's one (I don't know the seller, just giving an example) on ebay:

http://cgi.ebay.com/ws/eBayISAPI.dll...m=3102858 289

This is the EXACT same regulator I'm using, and the one Dave Gomberg
sells (or at least sold me) for $75 or so...

A CO2 tank should cost you no more than $50.00 or so from your local
gas supplier or welding supply store.

A needle valve can be purchased new for $20.00. I got mine from
Marine Monsters, but I've heard they are having some trouble. If this
is still the case, I know I've seen several other places selling
needle valves for about the same price. I know Robert over at
Aquabotanic sells one for $18.00

A reactor can be made cheap using a small powerhead and a gravel vac
tube.

The only part that really involved any swearing for me was finding
tiny little adapters to fit my needle valve to the regulator. Many
of the needle-valves I've seen lately just have hose-barb fittings on
both ends, and most reactors come with hose-barb fittings, so it's
pretty easy.

Possibly a bigger issue with the Dave Gomberg high pressure system, if
it's the same as when I bought mine several years ago, is that the
tiny little Eheim diffusor isn't very effective in large tanks.


It's fine in my 75 gallon. I believe Chuck uses a wet-dry filter, which tends
to lose a lot of CO2. The Eheim will probably be fine with any "normal"
filter.

I am considering switching to some kind of reactor, or injecting directly into
the filter intake, in hopes of lowering the maintenance required. You do have
to rinse the Eheim diffusor's ceramic disk every week or two, to keep the CO2
bubble size small.

I purchased one of these systems in July (inc. needle valve), and have
been more than pleased with it on my 29 gallon tank. I was willing to
spend a few extra bucks for someone else to figure out all of the
various fitting sizes etc. and save a day of driving from welding shop
to welding shop.


Yes, that's how it was for me, too. I did a lot of research, and found several
Web pages describing how to do it, but I still wasn't sure what kind of
regulator to get, what kind of fittings were needed, etc. The people who sell
CO2 refills have no clue about using CO2 for fishtanks, so they weren't much
help. I probably wouldn't be using compressed CO2 today, if Dave didn't offer
complete kits meant for planted tanks.

i've found that the little rena 2" diffusers do a good job of maintaining a
small bubble size over an extended period. i've tried several other
"airstones" as well as limewood diffusers and they all seem to generate
large bubbles from the start or soon thereafter.

when i say small i mean bubbles small enough that 70% (approximately)
disappear within 8" of water column. with a 75G i don't think anything would
make it to the top if the diffuser was at the bottom.

if you use the rena make sure to trim the lip of the rubber at the top
otherwise it will collect the fine bubbles into larger ones.

Alright,

By a tank dump then, you are talking about alot of co2 *gas form* comming
out all at once and sufficating the fish?

I thought you meant liquid comming through and contaminating the water. I
called the welding shop, where I bought the co2 tank, and they said the
liquid could only come out if there was a tub inside the tank, which is
normally only used for large tanks *50gal+* or Paint Ball Tanks.

Which needle valve do you prefer, or is there such a thing?

Thanks!

The product is perfectly fine. The problem is that the system doesn't
use a needle valve.

But even without a needle valve, the system is SAFE, and works fine.
The issue is what is known as an "end of tank dump". Co2 regulators
are intended to operate with a tank pressure of 800-2000 psi (CO2
pressure will never get that high, it's usually around 800-1000psi).
On the regulator, the high pressure gauge is marked in red from
0-600psi. This is because, when the CO2 runs out, the tank pressure
drops down. The regulator is unable to properly regulate when the
tank pressure is very low. In theory, anything below 600psi is a
problem. In practice, I've run my regulator (from Dave Gomberg) down
to 300-400psi with no "dump". But in any case, once the pressure
drops below the regulators minimum, the regulator looses the ability
to regulate the output properly, and the output pressure will rise.

Since with the "high pressure system" the pressure directly controls
the bubble rate, this rising output pressure results in a CO2
overdose.

At the extreme end, the regulator can completely loose control when
the tank pressure drops very far. At that point, it would vent all
the remaining CO2 in a sudden burst.

For all of these cases, simply adding a needle valve will provide a
safety net.

But, if you keep an eye on the tank pressure, it's easy to notice
BEFORE the tank pressure drops very far. Unlike watching your car's
gas gauge, the CO2 pressure will remain constant (around 800-1000psi
depending on the temp) until the tank is 99% empty. When the CO2 tank
is filled, the CO2 is under pressure, and is in a liquid form. As
long as ANY liquid CO2 remains in the tank, the pressure stays at that
800-1000psi. Once all the liquid is gone, the pressure will start to
drop.

On my tank, with a fairly high CO2 flow rate, I would get about a week
from the time the pressure first started to drop, till it reached the
600psi mark. So even without a needle-valve, if you glance at the
CO2 pressure once every few days, you will see it in time to prevent a
problem.

On my system, with a needle-valve, I intentionally let the pressure
drop all the way down. I run the regulator pressure at about 6psi
normally, and then control the bubble rate with the needle-valve. I
usually have a bubble rate around 2-3 bubble per second. As the tank
pressure dropped below 300psi, the output pressure rose up slowly to
about 15-20psi. I never saw a true "end of tank dump" with a big
spike in output pressure. And the bubble rate (because of the needle
valve) didn't increase much, less than 1 extra bubble per second.

Possibly a bigger issue with the Dave Gomberg high pressure system, if
it's the same as when I bought mine several years ago, is that the
tiny little Eheim diffusor isn't very effective in large tanks. In my
75g, I was unable to get acceptable CO2 levels using it. I ditched
the eheim diffusor, added a needle-valve, and built my DIY reactor,
and I've been very happy ever since.

Yes. It doesn't actually sufficate the fish, but the end result can
be the same...

No. Any liquid CO2 that did come out would quickly expand into gas,
so it wouldn't really "contaminate" the water. But liquid CO2 can't
come out of the system unless the tank was a "syphon" tank with a tube
specifically built into the tank to draw up liquid, or maybe if you
inverted the CO2 tank. The liquid CO2 would probably be stopped by
the regulator anyway. And the regulator might be damaged by the
liquid CO2. (it freezes the seals, etc)

I just bought one sold for planted tank use. I don't know anything
special about them. Buy one from Dave Gomberg, or Aquabotanic, M3.
You might be able to find one somewhere else for a few bucks cheaper,
but I wouldn't know what specs to look for.

Thanks Chuck!

I got a needle Valve and Check Valve from Robert at Aquabotanic. He was a

I called the local welding supply and they said they had fitting for the
regulator, so I guess im gonna be set haha.

Thanks Everyone!

Sounds great. There's always someone helpful around here if you hit
any questions. One good suggestion I heard regarding setting up a
new CO2 system: When you first set it up, be sure you will be
available to monitor things for the first 24 hours. Start out with a
low bubble rate, don't try to drop the pH too far too fast. Adjust it
a little at a time, until you get the pH where you want it.

Im planning on doing a Co2 setup, yes. If so, what types of lighting would
I need. I would like 3 watts per gallon - or close to it.


That's quite a bit of light output. Here's my setup and story.

I've had tanks off and on since I was a teenager (now 46). Presently
I've got a 75G AGA tank (48L X 18D X 20H). I started the planted tank
expedition with just the 2 T12 tubes that fit in the AGA dual tube
hood, and no type of co2 injection whatsoever. The plants didn't do
well at all. I figured that they needed a little co2 so I sprung for a
carbo-plus. While this device might work well in a smaller tank I
noticed that there wasn't much of a co2/ppm increase even with it
running full bore (ph and hardness didn't change at all) with it's
use. The replacement cost of the carbon blocks isn't cheap either. So
I figured that it was time to bite the bullet, and go for broke, if I
was going to do the "live plant thing". I got the retro 2x55w kit from
ahsupply. I followed the directions to the letter for the
installation. I made the mistake of turning it on while it was "bulbs
up" to see just how bright it actually was. My eyes haven't been the
same since. Ya need a welding hood to look at this setup!!!!! I also
sprung for all the necessary items needed for compressed co2
injection. I got a 5G tank from a local welding supplier, and the
regulator, hoses, needle valve, and diffuser from Dave Gomberg
(wcf.com). I got a bunch of different plants from one of the various
sources on the net and set up my tank with the real plants. They did
well for the first month, and as their natural reserves were depleted
they started to decdline in growth and looks. I got a horrendous algae
outbreak, and figured that I wasn't adding fertilizer in enough
quantity, and frequency to keep the plants out competing the algae. I
upped the dose rate, with reservation that I might actually give the
algae more food to dine on. To my amazement the algae almost
disappeared in a matter of days, and of course the plants took off and
look much better now that they are getting the nourishment they need.
So I guess in closing I'm stating that with my 75G I'm having good
luck with 110 watts of light. The plants pearl nicely and if there is
a broken leaf vein there is usually a steady stream of o2 bubbles
rising to the surface. Even with all of the info available on the net
from seasoned aquascapers your setup is going to be a trial and error
process. For those that care, here are the tank particulars...

ph 7.4-7.6

hardness about 7-8

ammonia, nitrite, and nitrates all measure 0.0

2 big boxes of laterite intermixed in gravel substrate

filtration is a Magnum 350 pro with marbles in the charcoal canister
to keep it from collapsing, as the filter sleeve loads up.

water changes are about 25% every other week with a complete filter
cleaning (bio wheels are NEVER cleaned) and about a tablespoon of salt
added per gallon (4tbs per change). No ill effects with the added
salt.

fertilization is liquid via water column, as well as root tabs.

Mobile inhabitants.
3 wild angels
tetras, 6 head and tail light, 5 cardinal, 1 blue
4 silver hatchets
2 pineapple swordtails
2 black sailfin mollies
4 yo-yo (pakastani) loaches
2 do-jo (weather) loaches
6 zebra danios
3 glass cats
2 guppies
2 leopard corys
probably something else I'm forgetting since the tank lights are
presently off.

I also had a pair of kuhli loach juvies but they were so small that I
think they were harassed to death.

I also tried a pair of apple snails but the yo-yo's made a meal out of
them

had fiddler crabs with a biosphere for quite awhile. They did well
except for the one that managed to get out of the tank. The beagle had
a ball with it for awhile!!!



Planted inhabitants
2 amazon swords
2 dwarf hairgrass
1 java fern on driftwood
2 crypt wendtii
1 anubias nana round leaf
1 madagascar lace
5 anacharis
15 ambulia
15 green cabomba
5 hornwort floating (since removed) messy real messy
5 corkscrew vals
5 microswords

all inhabitants appear healthy and happy since I upped the fertilizer
