OCTO Sumps are truly a work of art. Solid acrylic has been fused together by hand and then compartmentalized for the perfect fusion of form and function. A dedicated protein skimmer (and/or reactor) chamber, a return pump chamber, and a freshwater reservoir for your auto top-off (ATO) system are all built in with meticulous craftsmanship.
A filter sock holder is also built in for what has become the standard in mechanical filtration for sumps. But the engineers at Reef Octopus observed the trend of using automatic filter rollers for mechanical filtration so all units are designed to accommodate the Klir Fleece Filter Di-4 (sold separately) so you can enjoy maintenance-free aquarium filtration for months at a time.
Keep annoying microbubbles bubbles out of your display tank and salt creep out of your sump and stand with the OCTO Sump’s bubble-diffusing intake chamber and lid. A lid is also included to cover the freshwater reservoir chamber to slow evaporation.
Another hobbyist-friendly feature is the ability to adjust the water level in the sump. All OCTO Sump models have the ability to adjust the water depth inside from 5.1” all the way up to 9”. This makes it super easy to set the right depth for your protein skimmer to perform optimally without the need to buy a separate stand to raise it.
Reef Octopus OCTO Sumps are made to be your “forever” sump. A sump that is built like a tank and packed with useful features and rugged good looks. A sump you can be proud of. A sump you’ll want to post on your Instagram and show off when friends come over. We believe OCTO Sumps will meet and exceed all your expectations because they were built by reef hobbyists, for reef hobbyists. Thank you and enjoy!
