At 2ml/gal, I noticed no symptoms on animals when I tried this as an experiment.what effect does peroxide have on animal inhabitants, other than supplying o2?
At 3.5 ml/gal I noticed some stress on my snails (almost looked dead, but they pulled out of it later), but no stress on shrimp.
I stopped at that point. I know one person who dosed 4 ml/gal and lost nearly all snails. Still, there was no reported affect on other tank inhabitants.
Still, "peroxide" is not a cure, just another of many treatments to help clear out what's there after you've fixed the issue that lead to algae in the first place.
