I dosed the equivalent of 3ml per gallon in a 125 (about a cup and a half), dumped straight into the tank, and lost all algae except some GSA (I'm guessing that's what it is) on some driftwood. A week later I dumped 2 and a quarter cups (better than 4.3ml per gallon) straight in. The algae on the driftwood is still doing fine:mmph:. Almost all of my ramshorns and every single pond snail died#-o. Glad to see the pond snails gone, but hope the ramshorns make a bit of a comeback soon. No harm has been noticed on the plants or to the fish.

I put a hob filter on while doing this to keep the water moving (normally have no filter) and did it when lights were going full blast.

Regarding the breakdown of h2o2, I recall that light energy is the main catalyst.

Regarding the cyanobacteria, if you try it sure enough let us know how it works. I've not really had much stuff like that to try and kill because two evil outbreaks out baterial disease popped up from "adopting" fish and I had to dose antibiotics, so everything was wiped out.

Mikslik - I'm not sure it'd be nearly as bad for shrimp as it is for snails, but davemonkey and kwc1974 had tried this and I think both of them had shrimp at the time??? I might be mistaken...

what effect does peroxide have on animal inhabitants, other than supplying o2?

I used better than 4ml/gal one day after using 3.??ml/gal and killed 99% of the snail population. The fish seem fine, except a couple zebra danios have nipped-looking fins, though they nip at each other regularly, so this may not have anything to do with it.

I'd say 2ml/gal dosed two consecutive days killed 90% of my BGA, along with 90% of my anacharis, hornwort and milfoil.

I noticed pretty similar results on some of my mosses. While some pockets of them were untouched, others were nearly obliterated (using the 3.whatever and 4ml concentrations back to back).

However, I've just put in a significant order to InvertzFactory and hopefully can rely on critters to do my algae work from now on. Even though I did not many plants (yes, some did in fact perish), I lost 30-50% of my leaves (depending on species) and 100% of the leaves on my 2 red lotus. They're coming back as we speak, and now I have another baby coming up next to one of the mama plants.

H2O2 is awesome as a treatment, but overdoing it can cause more harm than good IMEO (E becaue I figure after blasting peroxide into the tank in such quantities I've killed enough plants to have formed an educated opinion). Buy some otos and other algae lovers; they're relatively cheap and make great tank additions.

P.S. - After all of this, the green water STILL did not vanish. If the conditions exist to support algae beyond the plants' capabilities, there really is no quick "cure" to your woes. Be patient, find the problem, and be patient some more...

Oh yeah, what they said- it is the normal 3% strength you get at the pharmacy as a mouth wash/wound cleanser.

I can only imagine what 30+% would do. :-O

HAH!!!!! I bet that'd make for some AWESOME pearling...up to the point that the driftwood begins to turn white and everything else dissolves!

I put a couple cups of 36% in a 75 removing the fish first and leaving the filters on. It killed all of my MTS and even in tanks where I used a catalytic H2O2 doser, I am still MTS free. However with the two cups "treatment", there was a lot of foam. I had lowered the water level as low as I could to keep the filter running, about six inches, but the foam billowed up way higher than that and like in some Lampoon movie, kept rising out of the tank and onto the stand and the concrete floor. There was enough peroxide left in the foam to slightly lighten the wood stand and the concrete.

Dang Rhotophyta! I was just kidding! Thanks for taking the initiative to actually try it out at such a concentration so we can get an idea of what it'll do.
