Snails/calcium/feed

[washefuzzy]

Hello it's question time again. My ramshorn snail seems to have a white spot with a hole in it. I suspect they need some calcium in the aquarium. how do I do this?
How often should I feed the snails. I've been giving them, in the evening, a bit of a spirlina algae tablet and either cuke, boiled zuke,collards. so far.
Thanks for your help forthcoming.

You can buy liquid calcium at drugstores, or place calcium blocks(pet stores sell) in the tank, or cuttlefish bones(pet stores sell, they are for birds) in the tank or I could sell you some hard water . hth

Okay, false alarm! Now I have my glasses on and it's daylight I can see the shell is just a little white in a spot from his opening. So maybe it's just new stuff but there is no hole. Phew!
Sas thanks for the offer. Thrrrrpt!
