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 1⁄4" cell cast acrylic. The side and bottom panels are clear and opaque black acrylic is used for the top and interior baffles.
The included brackets 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 Scrubbers:
Sump Model
CWT 25 CWT 35 CWT 50 CWT 55
Clear Water Scrubber Model
CWS-50 CWS-100 CWS-200 CWS-300
Remaining Footprint 7” x 7”
17.5" x 6" 20" x 8" 24" x 8"”
The remaining footprint with scrubber installed allows room 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.
Compatible Filter Socks/Fleece Rollers:
4" Felt Filter Socks with Plastic Ring 4" Klir Fleece Filter Roller

An algae scrubber is a water filtering device which uses light to grow algae; in this process, undesirable chemicals are removed from the water. Algae scrubbers have allowed saltwater and freshwater aquarium and pond hobbyists the ability to operate their tanks the way that oceans and lakes operate by using natural filtration in the form of primary production.
Installation Instructions:
1. Find a suitable place for the scrubber to be placed that allows it to freely drain into your aquarium’s sump.
For best results remove the main and emergency drain bulkheads and install them in reverse (flange and gasket inside of the scrubber body).
Plumb the drain into your sump using 1" soft tubing or PVC.
Plumb the emergency drain with 1/2" PVC or soft tubing allowing it to drain into your sump. We prefer to keep the emergency drain a few inches over the water level making the water crash into the sump that produces an audible noise, letting you know when something is not correct with the main drain.
Attach 1/2" soft tubing to the included feed barb fitting. We recommend soft silicone tubing for this application.
Adjust the flow over the algae screen so that an even sheet of water flows down the screen. Flow adjustments can be made with either a ball valve on the feed line or with a DC style pump.
Plug the LED light power cord into a timer or aquarium controller and program it for a 12-hour daily photoperiod. We recommend illuminating the algae scrubber in an opposite lighting cycle than your display tank to help stabilize your aquarium pH.
8. Monitor the algae growth and after a few weeks the algae will be ready to harvest.
