It’s designed to rapidly lower phosphate levels — a common culprit behind algae blooms — and thus supports clearer water, healthier corals, and improved overall tank stability. When dosed correctly into a high‑flow area, you may notice a temporary cloudiness or “smoke” — a sign the chemical reaction is trapping phosphates. Once filtered out, phosphate levels remain low, helping prevent nuisance algae and promoting optimal reef conditions.\u003c\/p\u003e","brand":"Marine Fish Shop Online","offers":[{"title":"Default Title","offer_id":52044863013205,"sku":null,"price":27.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/2278\/0501\/files\/agentgreen_da6b9e9b-ce25-49cd-b9d3-b2bc681f3c04.webp?v=1765226656"},{"product_id":"blue-shark-waste-control-473ml","title":"Blue Shark Outbreak Waste Control 473ml","description":"\u003cp\u003eBlue Shark Waste Control is a biological aquarium cleaner that helps reduce organic waste build-up by using beneficial microbes to break down sludge, detritus, and decomposing organics within the tank.
