It seems, from all the research I can find, as though anything below
10ppm is safe for bacteria and fish. Invertebrates might be more
sensitive, but I've repeatedly dosed up to 15 ppm with no visible
ill-effects on fish or snails. With 3% peroxide, adding 1 tablespoon per
8 gallons will yield very close to 15 ppm.
