    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 ΒΌ" 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 contains a 1" slip bulkhead and a flexible-use media section and comes standard with a removable Filter Sock Tray.  The media section of the CWT 25S Sump is compatible with the Clarisea SK-3000 Automatic Filter System (requires conversion kit for the Clarisea SK series, available soon from CWT Aquatics).  The standard tray is compatible with standard 4" filter socks and the Klir Di-4 Fleece Filter Roller.


    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.
