Black Aquarium Sand Weight:35lbs 1lb per gallon of tankThis Black Aquarium Substrate is perfect for aquascaping to make any plant or fish pop against a dark background.

Many carpeting plants prefer a finer substrate to attach their roots to, allowing them to grow quickly and healthy. The sand is composed of silica with no added dyes, colors or treatments. There may be some harmless residue, I recommend
