Reef sumps give you greater control over your tank. They help clean the water of accumulating pollutants, provide you a safe place to pour in additives, and allow you to hide equipment like heaters, protein skimmers and monitoring probes away from the display tank.

Here at BulkReefSupply.com, an Octopus Reef Sump is all you need to keep your tank inhabitants healthy. They are available in small, medium, and large sizes, and they all come with a built-in mesh filter sock.

We also have Octopus Refugiums that are great for reducing nutrients like nitrate and phosphate in the tank. It also maintains large population of pods for mandarins or other fish. We have these available in 14" x 4" x 12", 18"x 4"x 12", and 24"x 4"x 12" dimensions.
