The Filtration Drop1.4 Drop In Upflow Algae Scrubber is a revolutionary filtration system designed to maintain the health and clarity of saltwater aquariums. This compact, drop-in filter media works by promoting the growth of green hair algae, which effectively removes excess nutrients from the water, including nitrates and phosphates. It operates on both 120V and 240V power supplies, ensuring compatibility with a wide range of setups without the risk of overflow. The Drop1.4 features an injection-molded case for durability, along with 17 square inches of rough Green Grabber® surface area designed to absorb nutrients from daily feeding regimens. This innovative algae scrubber is ideal for aquarists looking to simplify maintenance and improve water quality in their saltwater tanks.
