The IcaCap PRO Algae Turf Scrubbers are designed as a plug-and-play solution for battling 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, the PRO Hang-On Algae Scrubber feature hangs directly on the back of the aquarium-- no sump or plumbing required! An IceCap EVO feed pump is also included so that you can set up and go in true plug-and-play fashion.




The IceCap PRO HOB Algae Scrubber is designed to be placed directly on the rim of your aqaurium. Water is fed into the scrubber by the included IceCap EVO water pump, which is placed within the aquarium. The water going into the scrubber is trickled down onto a screen that is illuminated on both sides by a powerful field of LED lights. As algae begins to grow on the screen, it “scrubs” the aquarium water of excess nutrients, resulting in less algae growing inside the display tank. Once the screen is covered in algae, it can be “harvested” by removing a sizable portion, thereby removing the contaminants from the system.



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



Many hobbyists prefer to run their algae scrubbers on a reverse daylight schedule to help stabilize the pH in their aquarium water. This can be accomplished 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 the display tank lighting.
