Well I did sell it. You can analyze that for yourself:-) But I do have
access to much more accurate test at the moment and have been satisfied with
the trends and levels I've used over the years.

I have similar beef's with them but if hungry they will eat it.
I've watched them try to eat the algae balls also. They certainly do eat M
matogrossnese var green. That I'm 100% certain of. Young ones seem the best.
Put the big ones out to pasture:) Bring them down to the LFS.

I'd say 5 total or so should be enough.

Humm, since you are feeding well(?) this might help but I think uptake will
pretty high if the K, PO4, Traces, CO2 are good for NO3.
NO3 is a thorn along with CO2 for algae and if NH4 appears that kicks off
the whole algae game good.

Well the old turkey baster method then. Good for the lazy in you and also
should work well. Turn off all flow in the tank for 5 minutes or so.
Fill that turkey baster with 5mls or better yet a nice disposable 5 ml
pipette and squirt the H2O2 right on the area infected very, very slowly.
This high concentration of H2O2 will kill the local area before it dilutes.
Some folks have tried this with good success. I have not tried it yet since
I have mainly been working with other algae lately. Seems like a good lazy
method for spot control.

You'd be surprised. All the fish waste, reduced flow, plant matter and other
bio loading does what?

That's not that bad.

Well faster cars often give bumpier rides till you get the hang of things.

They have made it through some pretty high CO2 levels for me. That increased
filtration, good O2 production, low absent NH4 I think is the key to most
critters. Low O2 seems to be the worst issue for critters, I've pushed them
up to 50ppm or so. They are all alive still.

Well, you'll get balanced out. Patient and lazy may take awhile but it'll
get you there. Impatient and lazy:)? Bad combo. Try the baster method and
see how you like that. Don't use more than 5 mls or so at a time(wait 12-24
