Description

Onyx Sand is a specially fracted, stable porous gravel for the natural planted aquarium. Being carbonate wealthy, Onyx Sand provides an advantage to any plants in a position to utilize bicarbonates. Even though ideally suited to planted aquaria, it can be used in any aquarium environment. Onyx Sand is most effective when used by myself as an integral substrate bed, but it can be mixed with other gravels. Gravel modifiers such as laterite aren’t vital. Onyx Sand isn’t chemically coated or treated but does have a slight buffering capacity that can raise pH by 0.1 – 0.5 pH units (depending on source water characteristics).
