Start controlling nutrients naturally and more effectively than ever before. CWT Aquatics sumps and Clear Water algae scrubbers come together to create a filtration powerhouse with a sump specifically designed for algae scrubbers.
Clear Water CW-100 Algae Turf Scrubber
Recommended for tanks up to 125 gallons
Algae turf scrubbers (ATS) use naturally growing algae to combat nutrients and have been used for many years now with great results. Many reefers that have been using them do not use any type of protein skimmer or expensive phosphate removal media to combat nutrients because scrubbers work very efficiently and can be added to almost any saltwater or freshwater system. As algae grows it will "lock" up nutrients in its structure and by harvesting the algae you are removing nutrients and other undesired chemicals from your tank.
The feed for the scrubber can be done with a stand-alone feed pump or manifolded from the primary return pump. Water will then flow over the algae screen that is blasted with high power red/blue LED lights that encourage algae growth and then the water will flow into the main drain fitting and back into the sump.
Maintaining the scrubber only takes a few minutes every one to three weeks to harvest the algae that has grown on the screen. Removing the horizontal union and rinsing the screen under a faucet will help knock a majority of the algae off the screen to be disposed of. Removing all the algae from the screen will lead to a slow start of the next batch and by leaving a small amount of algae on the screen you will help seed the next batch allowing it to grow faster. You may need to use a soft bristle brush (toothbrushes work great) to clean the slot that the screen fits into every now and then.
CWT 35 Sump
CWT sumps are ready for the latest and greatest filtration tech, featuring rails designed to accept a range of waterfall-style algae scrubbers and a sock chamber built to accomodate the Klir 4" automatic filter roller. 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 M2 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.
*With scrubber installed, there is a remaining footprint of 17.5" x 6" 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.
