Live sand or substrate is a great benefit for filtration in your saltwater aquarium and will help build beneficial bacteria allowing you to provide a more stable enviroment or reef tank. Saltwater aquariums generally use live sand when first starting up, but more people have started using bulk dry sand also.
Using live sand or substrate will increase your biological filtration in your system allowing you to have a larger bio load. It will grow bacteria just like live rock to consume nutrients and ammonia from your system. We carry white and black live sand, plus we even carry bulk dry sand in stock. We have a full selection of live sand for sale, and can get any living sand you would want. If your looking to setup a saltwater aquarium live sand is one of the first things you will wanna add to your tank.
