IceCap Algae Turf Scrubbers use algae as a natural water filter to remove excess nitrates, phosphates, and other pollutants from your aquarium water. Rather than having algae grow uncontrolled inside your display tank, an algae scrubber allows you to grow algae in a controlled setting where it can be easily removed—thereby removing contaminants from your tank in the process. This all-natural form of water filtration can reduce and even eliminate the need for water changes. Best of all, algae scrubbers are safe for use in freshwater, saltwater, and reef aquarium systems.


Note: This reactor is for external use only and designed to be placed outside your sump or other filtration system. It will require drain plumbing (not included) and basic plumbing knowledge for installation.




IceCap Algae Scrubbers are designed to be placed outside your sump so that the water flowing through the unit can drain back into your normal filtration system. Water is fed into the scrubber by the included EVO water pump. The water going into the unit is trickled down onto a screen that is illuminated on both sides by powerful full-spectrum LED lights. As algae begins to grow on the screen, it “scrubs” your aquarium water of excess nutrients—so you’ll have less algae growing inside your tank. Once the screen is covered in algae, you “harvest” it by removing a sizable portion, thereby removing the contaminants that fueled its growth from your system.



Remove the top and loosen the quick-release union on the side. Lift the pipe and algae screen out and run them under water in the sink. You can use a credit card or similar scraper to remove stubborn buildup. Be careful not to remove all of the algae from the screen, as this will slow growth when you put it back into your system. Leave some algae behind to seed the next batch so that it will grow faster. Under normal circumstances, you will be harvesting algae every 1-3 weeks.



Many hobbyists prefer to run their algae scrubbers on a reverse daylight schedule to help stabilize the pH of your aquarium water. You can accomplish this by plugging the LED lights into a timer or aquarium controller and programming it for a 12-hour daily photoperiod that runs opposite of the daylight schedule of your display tank lighting.



IceCap Algae Turf Scrubbers are equipped with an emergency drain fitting in case the main drain ever gets clogged with algae.
