The Sea Side Aquatics New Cone Skimmer ES2 is a high-performance protein skimmer designed to efficiently remove dissolved organic compounds from your saltwater aquarium. Utilizing a sophisticated cone-shaped body, this skimmer concentrates the air-water mixture to produce a stable, dense foam, effectively pulling proteins and other waste products out of the water column before they can break down into harmful nitrates and phosphates. This process is crucial for maintaining superior water clarity and a healthy, stable environment for your fish and corals. At the heart of the ES2 is the powerful and reliable PSK1000 pump, engineered to chop massive amounts of air into fine bubbles for maximum surface area and contact time. The unit stands at 21.65 inches tall and fits comfortably in most sumps with its compact 13 by 10 inch footprint. It features a 1.5-inch outlet for smooth water return and is robustly built to handle the demands of aquariums rated for up to 300 gallons, making it a formidable piece of filtration equipment for serious reef systems. This skimmer is the perfect choice for the dedicated reef aquarist with a medium to large-sized system who demands uncompromising water quality. Its high capacity and efficient design make it ideal for heavily stocked tanks or systems with sensitive SPS corals that require pristine conditions. If you are looking for a reliable, powerful, and space-conscious skimmer to serve as the primary filtration workhorse for your reef aquarium, the Sea Side Aquatics ES2 is an excellent investment in its long-term health.
