snails and co2
i just put in a home made co2 diffuser into my tank. the plants are going wild, and i can see them photosynthesising and breathing; quite a new exerience, but my snails have slowed down, and i think one might even be dying. they used to zoom around the tank really fast, but now theyre just sitting there. do they not like co2? my fish are doing fine and the co2 levels are optimal.
