Octo Reef Sumps offer attractive design, the versatility and features you need, and they’re built to last. Each Octo Reef sump is hand-built from solid acrylic for years of trouble-free service. They’ve got you covered with plenty of room for your skimmer and return pump, and they also feature a built-in ATO reservoir.
 
Features
Reef Octopus red color accents (matches other Reef Octopus products)
Solid acrylic construction
Adjustable water depth from 5.1” to 9”
Dedicated protein skimmer (and/or reactor) chamber
Dedicated return pump chamber
Dedicated freshwater reservoir with lid for ATO
Bubble-diffusing intake chamber with lid
Built to accommodate roller filter mats like the Klir Filter Di-4
 
One of the standout features is actually the filter sock compartment. Of course, if you want to run standard 4 inch filter socks, you definitely can, but if you’re looking to upgrade to a lower-maintenance option like one of the new Klir rollermat filters, Octo Reef sumps have been designed with this in mind. The filter sock chamber has been built with an overflow designed for operation with the Klir DI-4 fleece filter system.
 
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.
 
Get it right the first time and go with an Octo Reef sump. Their meticulous craftsmanship and hobbyist-minded features ensure this will be a sump you can be proud of.
