What is Texas Holey Rock?

Texas Holey Rock is Honeycomb limestone.

The limestone occurs in the state of Texas and is interspersed with chambers and holes.

It is composed of dolomite and limestone.

The rock contains carbonate minerals calcite (CaCO3) and dolomite  (CaMg[CO3]2).

Interestingly, the rock developed over thousands of years as minerals were deposited on top of each other.

The holes were formed when the rock was moved by the earth and fractured.

This allowed water to flow through and then mix with sulfurous gases in the cracks, which in turn created holes as the limestone, which is soluble, dissolved.

No two rocks are the same because these rocks come in different shapes and sizes.

These rocks are very delicate and handling is of the utmost importance so as to avoid any unnecessary breakages.

For this reason, these rocks are a rather pricey accessory.

One of the main purposes of this type of rock is to assist with raising the PH balance of an aquarium.  

When placed inside the fish tank, fish easily and freely move through the holes and crevices in the rock formation.

The stone has weathered holes and cracks.

These rocks are 100% natural limestone textured aragonite dry rock.

The rocks found on land, in the Texas region, do not have the milky white appearance.

Usually they are covered in dirt and debris and need to be cleaned.

It is believed that the employees of the establishments that sell this type of rock bleach the rock with strong white vinegar to give it that soft white appearance.

The rocks have different textures.

Some are smoother than others.

This means that some of the Texas Holey Rocks can be cleaned using a stiff bristle brush, while others require a much softer brush.
