Texas Holey Rock?

[lapin]

I had never heard of the stuff. I find it interesting that this is the only post I could find using the brand name Caribsea with Texas Holey rock. I was more interested in geological information on the rock but the internet is useless for finding real information anymore.
It has gone from having the best set of encyclopedias in the world at your disposal to having a complete comic book and **** collection.

What you have is bottom sediment layed down during the Cretaceous period when most of N America was cover by a shallow sea. Its is full of shells of the creatures that were living at the time. The rock is not a coral reef formation. It is a limestone rock that has been eaten away by acidic rain water. This forms holes and pockets in the rock.

Been using Texas Holey Rock it for 30 years with no problem. Check the systems in my signature.

I'm considering using Texas Holey Rock for my 220 gal set up. Do you have a picture of yours? Does the Coraline algae and critters like it? Thank you for your help!

Hi, I know this is an old thread but I want to pipe in for others who may be looking into this now. I'm a newbie with saltwater but I'm also a rock-hound. Texas Holey Rock is limestone. I'm using a chunk of it in my reef tank as a playground for small fish / invertebrates and I can say my 6 Line Wrasse LOVES darting in and out of the holes in the rock. I've heard it leaches some alkalinity into the water and helps with buffering ph - which I think is probably a good thing.
