So I bought my very first snail yesterday, a horned nerite: Eee so tiny! I have him/her in a planted 10 gallon will plenty of green algae to snack on and will be supplementing with algae wafers and the occasional raw vegetable. I read somewhere that CO2 in the water dissolves a snail's shell over time. I dose with a liquid CO2 so will it have the same effect? My plants don't NEED the CO2 but I'd like to continue using it if it won't hurt the snail. Thanks in advance!
