Coral sand is mainly used for decoration in the aquarium sea salt tank. A thin layer of white coral sand on the bottom of the aquarium will be very similar to the seabed environment and very beautiful. In addition, coral sand has many functions.

Many people don’t know that the sand we see is “dead” sand. After bleaching, the granularity and size are different. However, the coral sand  is deposited by dead coral. The main component of coral sand is calcium carbonate. A large amount of bottom sand will help stabilize the KH of the seawater in the aquarium. At the same time, coral sand is used as the bottom sand, which is also a good filter material.

Want to know how to use coral sand to build a more perfect aquarium sea salt tank? Then we have to talk about the DSB (deep sand beds) system. There is an essential difference between the DSB system and the thick sand bed established by ordinary “dead” sand, that’s the source of sand is different. The DSB system uses “live” sand from the seabed, which contains a lot of bacteria, tiny organisms, and worm eggs. And so on, to help the aquarium build a complete ecosystem.

As a result, in addition to beautifying the aquarium tank, coral sand can also fix the coral stone for landscaping. The most important point is that it participates in the ecosystem of the entire aquarium, decomposes some substances, and activates the water.

In the next program, we will tell you how to choose the size and model of coral sand. And how to arrange the aquarium tank.
