Can snails eat "live" off of live rock

[supermarvin76]

My snails are doing a GREAT job cleaning my rocks. But........I was woundering if they can eat the "live" off of my live rocks. Some of my rocks are now ALOT more white than I have ever seen them. Is this bad? Good?
Will they eat my Coraline alage?

I don't want to say no for sure but in my experience, as limited as it is, my snails haven't killed my rocks. Live means that the rocks are brought into the tank full of bacteria and such. Take the bacteria out and u just have rocks. The only thing my snails have noticeably eaten is some really pesty hair algae. My rocks are full of purple, green, and red color

Yeah i think youll be fine with the snails on the rock they'll just keep them clean

My snails have'nt hurt my LR either. They sure did a job on the algae

I noticed the same thing with my snails, I think it will not affect the rocks though.
