Default SAE's, Amano Shrimp, CO2

Thanks very much Leigh. This gives me some good info to work with. I have
ordered the SAE's and Amanos, and hope they will arrive Friday.

I did put in quite a few plants all at once.

I did some work in the tank yesterday, getting out the algae-infested
leaves. There are more to get out, and I may wind up doing some drastic
pruning and hope those particular plants will re-grow. There is not that
much algae left, but it cannot be removed from fine-leaved plants (like the
Foxtail which I really love).

BTW, I was very much helped by the recent thread on pruning techniques.
Thanks to all the helpful ppl here!

Will the SAE's grow and stop eating algae, and hogging food?


A lot of people claim they stop eating algae as they get older, but that

hasn't
been my experience. Even when they are babies, they still like fish food

if
they can get it. It doesn't keep them from grazing on algae. My SAEs are

huge
now. They do eat fish food, but they don't hog it. No more than any

other
fish, anyway. :-) And between feedings, they are constantly grazing on
thread-like algaes. They will take care of your black algae, though it

might
take awhile. (They prefer tender new growth, so they may not eat the

stuff
that's already established. But they will keep new algae from growing

in.)

Will there be
special problems/things to know about the Amano shrimp? I have read that
they will escape the tank if possible.


I haven't had any problem with them. I do add a couple of drops of Kent

Marine
Iodine to the tank for them, with each water change. I have no idea if

this is
necessary, but it's necessary for ghost shrimp, so I do it for Amanos,

too.

The thing I don't understand about CO2 is, I was told by Phyl at TAP that

I
wouldn't necessarily even need CO2 at all. But after I put the plants

in,
my pH shot up to above 8.0 from a normal 7.0.


I remember that. That was weird. I didn't have a problem with 2.24 wpg

over
my non-injected tank. The only thing I can figure is that you really had

a lot
of plants, or it was just because the bulbs were brand new. (New PCFs

produce
much brighter light for the first few hours of use. Generally, this lasts

only
for a week or two, as we use them.) Or maybe you didn't have enough

surface
agitation.

If I have a "low-moderate"
amount of light, do I need CO2 in the 25ppm range? Or is stability of

the
CO2 level more important?


I think any CO2 helps. Though conventional wisdom has it that CO2 should

be up
around 20ppm, the data someone posted here suggested the biggest benefit

comes
from boosting CO2 only a little -- to 7 or 8 ppm. More is better, but if
that's all you can get, it's still worth doing.
