Is Texas Holey Rock reef safe? I have quite a bit from my cichlid tanks, and while I don't plan on using it exclusively, I would like to use it as a base rock. Does anyone have experience with this? Isn't Marcos Rocks basically the same thing?

I would pass on it. It’s so dense and wouldn’t allow much surface area for biological filtration
Is that the only limiting factor? Anything I should be worried about chemically?
You have to be concerned with the composition of the rock and what could leech out that is potentially harmful to your tank.
I recently asked the same question about volcanic rock. It is extremely porous and I thought it might provide lots of surface area for nitrifying bacteria. My concern was what metals might be in the rock which could cause harm to the tank and it's inhabitants.
I set up a test tank and took a chance. So far, no issues; just a normal tank cycle. My next step is to add inhabitants... something hearty, like damsels.
ok, sounds good as i dont think it would be a problem
i would plan on getting an RO/DI unit or some way to get that quality water as you will not want to use tap water on a salt tank. Dont get me wrong, you can but sooner than later you will try and find out why your water parameters wont stay stable and the tap water would be at least one of the problems.

Call Jake at River City Aquatics in Austin. He has a very large display tank with some very nice pieces of this. Ask him or his staff if they have any issues.
How much THR are you using in those tanks?
I would agree with all this except the highly porous line, unless they mean the giant holes that go through the rocks are the porous part. This rock is dense eroded limestone.Caribsea Texas Holey Rock
