It is shell erosion. Snails can only make <"new shell material at the mantle">, once new whorls have grown in front of that shell portion the snail can't repair it. If you have soft water (or your pH drops below pH7 during CO2 injection) then it will get worse and eventually kill the snail.noticed these white patches on a few of them. Anything to be concerned with?
So how do people keep snails and run high tech tanks with co2? I’m in Essex with hard water, but recent co2 profile in my other tank shows drop to 6.7 (achieving the 1 point drop from 7.7)Hi all,

If you have hard water, where the pH <"never drops below pH7">, then it will remain the same and not get any worse.

I'm not a CO2 user, but the linked thread <"Nerite Snails in high tech"> has some discussion.So how do people keep snails and run high tech tanks with co2?
