I have not had the chance yet to put this in my tank but from looking at it i can tell you that its about as grainy as beach sand but it is not as small as like gecko sand.

I was nervous about converting my freshwater tank substrate from gravel to sand. I did lots of research on the subject and decided to make the leap. I am so happy I did! The sand looks more natural and clean. It is also easier to clean since most waste rests on top rather than sinking deep into the spaces between rocks. A simple pass with a siphon hose removes most all of the waste. I do gently stir the top layers of the sand periodically to prevent any gas pockets, but haven't seen this as an issue yet.

The Estes sand came highly recommended. You need to follow the instructions and thoroughly wash the sand to prevent cloudiness in the tank. I unloaded it into a bucket and continued to rinse several times. Once I first put it in the aquarium, a lot of the sand floated and the tank was still slightly cloudy. I was nervous, but after a few hours, it had all completely settled and have had no issues since.

My goldfish seems much happier and will dig and siphon the sand. I use sinking pellets and he easily eats them up and spits out the sand with no problem. Seems much happier with sand.

it arrived very quickly! I am very satisfied with my purchase. Although there were some holes in the bag and different colored gravel. I need to say this is a good product and I recommend it.

Awesome sand. Stays a pretty white underwater and doesn't turn light tan like some white sands do over time in the aquarium. The grain size is coarse but still looks sandy.

Perfect!
