Shell on apple snail thinning out!

[woodlands]

I've noticed that the shell on my apple snail is thinning out . Is there a way to prevent this condition?

Is it due to lack of calcium in the water???

think it may be cause by the acidity of the water

Check your KH and PH level......you need to increase your KH which I think its pretty low.

Check your GH. May need to add some Calcium into your water.

I bought 2 of these snails last weekend. Once I dropped them into the planted, one of them started nibbling on my BJ's root and leaves. Is it normal ? I thought this snail eat algae only. How do you keep them ?

Thank BClee for the site, it is very useful. Thanks guys for the response. My KH is 4 and PH is 6.9. I hv neon tetras mostly, cories, rummy nose so i keep the ph slightly acidic. let me try to increase the KH and see how. Thanks guys.
