true but really how much are you willing to do to save $

i know ive got the DIY bug also

but ive spent less than $50 for co2 for a canister system for freshwater. its not like its
my reeftank's calc reator.

I think that would eliminate all the positive aspects of DIY CO2.....

Yeah..it will foam...but it settles back down in a while...

Basically I use knox jello....a cup of sugar...mix in hot water...poor
water
into coke bottle...put in fridge till it gets hard....then put an inch
of
warm
water and yeast. It doesnt put out as high levels of CO2 as the
"normal"
methods...but it lasts forever....takes the yeast a while to eat
through...

PH swings dont seem to be bad.....I let the new batch go for like 2
hours
before
I swith the bottles...jsut so I'm sure its actually producing CO2....I
dont
really see any swings...any Day-night swings dont seem to effect the
fish...but
I dont measure, so I cant tell you what they are...

With high light, CO2...actually keeps PH crashes from happening. In
fertilized
high-light tanks, the plants will eat all the carbonate in the water,
if
you
dont have CO2...and your PH will crash...CO2 keeps the plants from
eating
the
carbonate.



Try adding a little sugar to the yeast and water added on top of the
Jell-O.
You can have the best of both worlds...quick start and a long even run.

Suggestion... from experience. Don't be lazy and mix everything in the
bottle. Jell-O will foam up if you shake it hard enough...;-)

I used medium tech approach for a while, before going all out on high
tech. Some thoughts:

standard gravel mixed half half with fluorite or laterite (can't remember
the difference) to cut down cost

Go ahead and mix if you like, but if it's that much cheaper, just drop
the special substrate. I have a beautiful planted 20gal with
run-of-the-mill coated gravel.

undergravel heating (I can get these cheap)

If you can get it cheap, whatever. I've never used it.

good lighting (this I can build myself so lots of light is not a problem)

Heh, I built mine myself too! Still ran me about $150 for 2-3 wpg!
Avoiding expensive lighting is IMHO, one reason not to go high-tech.

no CO2 injection
dosing, preferably not

As others have said, DI CO2 is easy. A lot less work than I thought.

Also, before CO2, I got by on weekly dosing quite nicely. A small dose
of fertilizer with a weekly water change would help out nicely. Even
with CO2, I don't dose daily.

tons of filtration (this I can also do myself so I can add as much
filtration as is necassary)

I kinda kick myself for going overboard with filtration. I should've
saved the cash and just got a smaller filter. Keep that in mind.

So how does that sound? Could I expect this to work. I don't mind sticking
to the easier plants and all I expect of them is that they grow, but their
rate of growth I'm not too concerned about (I basically don't want them to
die or always stay the same). Anybody else tried something similar, what
kind of growth did you achieve, did it last?

Yea, you can definately expect it to work. Pretty well if you stick to
basic stuff like you mentioned. Mine would've lasted nicely forever.
The growth was quite impressive at times, when it came to quickly
growing plants. Things like swords didn't do so hot until I added CO2.

It's very sustainable - should last forever. In my case, my desire to
mess around with more aquarium stuff ran out much more quickly ::-)
