IceCap PRO External Turf ScrubberIceCap Algae External Turf Scrubbers are an effective solution to battle algae as a natural water filter to remove nitrate, phosphate, and other pollutants from aquarium water. Available in three sizes.Fight Algae with Algae... NaturallyIceCap PRO External Turf Scrubbers use algae as a natural water filter to remove nitrate, phosphate, and other pollutants from your aquarium water without occupying precious sump space. 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. This all-natural form of water filtration can reduce and even eliminate the need for water changes.Features:Feed Pump and Hose Included*Naturally Combats Nutrients and Algae IssuesEasy to Harvest and MaintainIntegrated Internal 24V LED LightsEmergency Overflow ProtectionDurable Acrylic ConstructionMulti-Directional Input with ValveHow It WorksIceCap External Algae Scrubbers are designed to be placed outside and above the sump so that the water flowing through the unit can drain directly back into the sump. Water is fed into the scrubber by the included IceCap EVO water pump. The water going into the unit is trickled down onto a screen that is illuminated on both sides by a powerful field of LED lights. As algae begin 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.How to Harvest AlgaeRemove 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 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 it can grow faster. Under normal circumstances, expect to harvest algae every 1-3 weeks.When to Run Your ScrubberMany 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.Small External IceCap PRO Turf ScrubberItem #: IC-AGS-1EXTPRODimensions: 7 x 8.7 x 11.8in (LxWxH)LED Number: 2 x 6wTotal LED Wattage: 12wScreen Size: 8.5 x 6inWater Pump: EVO-1000 (20w)Output Size: 1in Slip PVCOverflow Protection Drain Size: 1/2in Slip PVCMax Flowrate: 250gphTank Rating: Aquariums up to 100galMedium External IceCap PRO Turf ScrubberItem #: IC-AGS-2EXTPRODimensions: 12.6 x 8.7 x 12.6in (LxWxH)LED Number: 2 x 12wTotal LED Wattage: 24wScreen Size: 11.8 x 7.4inWater Pump: EVO-1000 (20w)Output Size: 1in Slip PVCOverflow Protection Drain Size: 1/2in Slip PVCMax Flowrate: 500gphTank Rating: Aquariums up to 225galLarge External IceCap Turf ScrubberItem #: IC-AGS-4EXTPRODimensions: 16.5 x 8.7 x 12.6in (LxWxH)LED Number: 2 x 15wTotal LED Wattage: 30wScreen Size: 15.8 x 10.5inWater Pump: EVO-2000 (30w)Output Size: 1.5in Slip PVCOverflow Protection Drain Size: 1in Slip PVCMax Flowrate: 800gphTank Rating: Aquariums up to 350gal
