The Ph is 6.5, but I put eggshells in the tank hoping it will help. I also looked it up as long as it doesn't get bumped a lot or holes that it will grow the new shell fine
Umm did you boil and wash the eggshells first? You know what would help? conch shells :D I have 3 in my 20 gal, and some pretty shells I found on the beach, great fior a beach theme! GREAt for snails, raises hardness, Ph, and KH
snails need "harder" water. hard water means that there are minerals in it, like calcium which snails need to maintain a healthy shell.. also if the water is too acidic it can be eroding.
