I have a bunch of limestone rock and Texas holey limestone rock that I used in my cichlid tanks. Not sure if this is something you would want to use as base rock or not? I would accept trades for pretty much anything saltwater related. I used some in my 120gal and I think some of my initial algae blooms might have come from the use of the rock...but no problems now that it has coralline growth on it.

I have some very large pieces that I paid a pretty penny for with large holes and many pieces with lots of holes and some that are just filler rocks.

Let me know.
