"horn of plenty snails" hah! Cornucopia snails?
We started out with 10... never see any more than three at a time but now we have some rather large ones and some really tiny ones... so who knows how many may be in the tank.
It's H2S, Hydrogen Suflide, not HO2, Hydrogen Dioxide, that is the supposed bane of all life in an aquarium. I believe that the potential danger to the tank inhabitants from this source is far lower than some seem to think.
