For many marine and freshwater aquarists, running a dedicated macroalgae refugium is impossible due to space constraints or the lack of an under-cabinet sump. The IC-AGS-50PRO bypasses these limitations by packing high-capacity turf algae scrubbers into a compact, rim-mounted profile. By forcing your water column to pass directly over a targeted, highly illuminated growth matrix, the scrubber causes hair algae, film algae, and organic compounds to grow \u003ci\u003einside\u003c\/i\u003e the box rather than over your decorative display rockwork.\u003c\/p\u003e\u003cp\u003eOperation is straightforward and efficient: the bundled IceCap EVO-400 utility pump sits submersed inside the tank, delivering up to 105 GPH of water directly into the scrubber's internal spray bar. This water trickles down a heavily textured, laser-roughened mesh growing screen that is lit from both sides by high-efficiency photoperiod grow lights. As the algae mat matures, it acts like a sponge, pulling dissolved inorganic nitrogen and orthophosphates straight out of the water column. Scraping the screen clean every 1 to 3 weeks permanently extracts these bound pollutants from your system. This significantly reduces your dependency on artificial chemical resins and frequent, labor-intensive water changes.\u003c\/p\u003e\u003ch3\u003eKey Features:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eStabilizes Daily pH Fluctuations:\u003c\/b\u003e When programmed to run on a reverse photoperiod opposite your display lights, the algae's overnight photosynthesis consumes carbon dioxide, preventing morning pH drops.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eUniversal Rim Tracking Adjustment:\u003c\/b\u003e Adjustable mechanical tracking brackets safely accommodate standard plastic-molded or rimless tank edges ranging from 1\/4-inch to 1 3\/8-inches wide.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eDual Emergency Overspill Tracks:\u003c\/b\u003e Features a secondary relief pipe that handles high water levels if heavy algae growth blocks the primary drain slot, keeping your living room floor dry.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ci\u003e(Note: This self-contained HOB assembly arrives complete with the main black polymer reactor box, internal textured mesh grid, dual 6W LED light modules, a 24V DC power transformer, and an EVO-400 pump).\u003c\/i\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVerified System Performance Specifications\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cp\u003e\u003cb\u003eTarget Aquarium Rating:\u003c\/b\u003e Explicitly rated to manage biological loads on standalone systems up to \u003cb\u003e80 Gallons\u003c\/b\u003e.\u003c\/p\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"IceCap","offers":[{"title":"Default Title","offer_id":50483988693240,"sku":"IC-AGS-50PRO","price":225.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/6909\/5160\/files\/05d11987b5983ece9904e55aa62481f5.jpg?v=1789092615","url":"https:\/\/www.blueearthaquariums.com\/products\/icecap-50-pro-hang-on-back-turf-scrubber","provider":"Blue Earth Corals","version":"1.0","type":"link"}
