Seachem Clarity 250ml — Polymeric Water Clarifier To Clear Cloudy Water Using Advanced Polymeric Flocculant In Freshwater and Marine Aquariums
Seachem Clarity 250ml (SKU: 724960-146) is a water clarifier designed to clear cloudy water in freshwater and marine aquariums. It utilises an advanced polymeric flocculant to clump floating micro-particulates, silt, bacterial blooms, and organic haze into larger masses. Once aggregated, these larger particles are easily trapped by mechanical filter media.
Seachem Clarity is a powerful water clarifier that coagulates suspended particles to clear up cloudy or murky water in both freshwater and saltwater aquariums. Clarity is safe for freshwater and marine fish, invertebrates, live plants, and beneficial bio-filter bacteria. The 250ml bottle provides effective water clarification following substrate placement, maintenance, or bacterial cloudiness. It is safe for fish, plants, and invertebrates, with a recommended dose of 5 mL per 80 litres, and works best when combined with mechanical filtration to trap the particulates.
