Selecting the right sand: When choosing the right sand for your tank, it is important to keep a few things in mind.

How much flow will be in the tank? 
Aquariums with high amounts of water movement will require sand with a larger grain size. Smaller particles can be blown around easily.

What kind of inhabitants will you be keeping?
Many species do require particular types of sand, like gobies, jawfish, and wrasses. Fish and invertebrates that like to burrow or sift through the sand will do best with smaller particle sizes.

Will it be for a refugium or deep sandbed? 
Sand that will be used for filtration or refugium, we suggest using smaller particles that will give bacteria more surface area to grow and thrive on.




How much sand do I need? 

Below is a table of common tank sizes and how many pounds of Hawaiian Black Sand is required to achieve a certain depth. Results may vary depending on the aquascaping in your tank, overflow styles, and the specific tank manufacturer. We always recommend getting a little extra sand to make sure you have enough on hand when you are filling your tank.
