IceCap Algae Scrubber Pro - Medium The IceCap Algae Scrubber Pro - Medium is an in-sump algae turf scrubber for aquariums up to 225 gallons. It uses controlled algae growth on an illuminated removable screen to help export nitrate, phosphate, and other nutrients from aquarium water while keeping algae growth contained in the sump instead of the display tank. Medium IceCap Pro In-Sump Scrubber Overview This medium Pro model gives larger systems more nutrient export capacity than the small version while keeping the same in-sump plug-and-play style. Water from the included EVO-1000 feed pump trickles over the screen, where algae grows under dual internal 24V LED lighting. As the algae mat develops, it absorbs nutrients from the aquarium system and can be harvested to physically remove those nutrients from the tank. Medium Pro Turf Scrubber Features In-sump design places nutrient export directly in the filtration area. Rated for aquariums up to 225 gallons. Uses algae growth as a natural way to reduce nitrate, phosphate, and other dissolved nutrients. Included EVO-1000 water pump feeds the scrubber screen. Two 12W LED lamps provide 24W total DC24V illumination. Adjustable height design works in sump water depths from 4" to 10". Integrated internal LED lighting supports algae growth on the removable screen. Emergency overflow protection adds extra security during operation. Multi-directional input with valve allows flow adjustment through the scrubber. Durable acrylic construction is built for aquarium sump use.

Official IceCap Turf Scrubber Video Using the Medium IceCap Algae Scrubber Pro Place the scrubber in the sump, adjust the height for the sump water level, attach the included EVO-1000 feed pump, and confirm water trickles evenly across the screen. Run the LEDs on the desired photoperiod and allow algae to establish. When the screen is covered, remove the pipe and screen, rinse them under water, scrape away a portion of the algae, and leave some growth behind to seed the next cycle.
