The CWT sumps are the first sumps specifically designed to accept an algae scrubber, filter roller and DC return pump without complicated plumbing or unsightly tubing!

These high-quality sumps are MADE IN THE USA using ¼" cell cast acrylic. The side and bottom panels are clear and opaque black acrylic is used for the top and interior baffles which creates a clean, contemporary look that compliments any color scheme.


The included bracket and PVC rail system located in the center chamber supports compatible Clear Water Algae Scrubbers above the water level while still allowing enough space for a protein skimmer or additional filtration equipment.


The intake or drain chamber accepts standard 4" filter socks but is also specifically formatted to work with the Klir Fleece Filter Roller for maximum mechanical filtration and pristine water clarity. A 1" slip bulkhead located on the return chamber is aligned to fit directly onto the EcoTech Marine Vectra S2 DC Return Pump but will also work with a wide range of additional pumps.


All models feature a probe holder with 4 ports, JG fittings for dosing lines located in the return pump chamber, adjustable water level in the center chamber, black colored lids to prevent salt creep and bulkheads for both the drain and return pump connections.


Compatible Algae Scrubber:

With scrubber installed, there is a remaining footprint of 7" x 7" for a protein skimmer or additional equipment of your choice. When using a protein skimmer alongside an algae scrubber, we recommend downsizing your skimmer because of the reduced nutrient levels as a result of the scrubber.
