Solve your nutrient & algae issues

An algae scrubber is a water filtering device (not to be confused with a scrubber pad used to clean glass) 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: using natural filtration in the form of primary production.

Clear Water Algae Scrubbers & CWT Aquatics Sumps come together to create a filtration powerhouse

Start controlling nutrients naturally and more effectively than ever before.


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.

Clear Water Scrubbers are an external design that needs to be mounted higher than the sump of your tank for the drain to flow into. The feed for the scrubber can be done with a stand-alone feed pump, manifold, or through the drain of your aquarium and plumbed into the included 1/2″ barb fitting. 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 down into your sump. Clear Water’s scrubber was designed with a 1/2″ emergency drain fitting that will accept any excess flow if the 1″ main drain ever gets clogged with algae.

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.

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!

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.

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

Holds your scrubber above the water line while saving room for a skimmer or other equipment.

Control the depth in the center chamber with and adjustable weir using our reversible fence with the smooth or toothed side.

Includes intake and return bulkheads and John Guest fittings for dosing or top off lines. Return is designed for direct plumbing for EcoTech Marine Vectra S2.

Pod Hotel Copepod Haven

Do you ever see your copepods homeless, roaming the glass or rocks looking for a home? The Pod Hotel is the solution to their problems with six levels of vacant rooms ready for them to set up a temporary home in. If your aquarium does not utilize a refugium the Pod Hotel makes a great home for them without needing a bunch of real estate.

Each Clearwater Pod Hotel can be easily transported from your sump/refugium up to your display tank for a quick delicious treat that your fish and corals will love! Just turn on a bright light over the hotel and in a few minutes, the pods will scatter into their new homes. After they all take refuge in the hotel you can transfer it up to your tank and shake it around to disperse the pods or leave it for an hour or so to let them come out to explore the new territory on their own.


Dimensions – 3″ L x 3″ W x 2.125″ H
