If you're not familiar with Texas Holey Rock, it's a limestone rock made up of mostly calcium carbonate. Our current rock classifies as high-grade with a CaCO3 content of 82-88 percent

It's easy to know whether or not to use this in your aquarium. If your fish and other pets require a high pH level, then this rock is a good choice. If your fish require a low pH, then this is not what you want for your tank. The rock itself isn't harmful to any type of fish or aquatic pet, but when put in water, it reacts and raises the pH level rapidly.
The tank in the photo above is a Cichlid tank. You can see how Texas Holey Rocks create the perfect environment for this type of fish. The holes that occur naturally in these rocks bring much activity, and the calcium provides nutrients for everyone in the tank.

In addition to THR we have other decorative rocks. Dry Reef Rock, also known as Dry Live Rock, has the ideal texture and pitting for the growth of beneficial bacteria.
