Starting another saltwater tank?

Question

would it be ok to start a saltwater tank having live rock but with aqatic rocks

Answer 1

I have no idea what "aquatic rocks" are, so I won't comment on that.

Bare-bottom tanks have been done, and those with them have reported success with lower maintenance, but most regard them as rather unpleasing to the eye.

Answer 2

what do you mean aquatic rock?  There is some rock you can use but make sure you find out before you buy rock that it will not mess with the PH of your water.
