Excessive levels of these nutrients are primary drivers of nuisance algae outbreaks and can lead to the degeneration or death of sensitive corals. Beyond nutrient control, Phos Stop also binds organic compounds and heavy metals, such as copper, significantly improving overall water quality and clarity.\u003c\/p\u003e\n\u003chr data-path-to-node=\"3\"\u003e\n\u003ch3 data-path-to-node=\"4\"\u003e\u003cb data-path-to-node=\"4\" data-index-in-node=\"0\"\u003ePerformance \u0026amp; Technical Excellence\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"5\"\u003ePhos Stop is engineered to bind unwanted substances securely, ensuring they are not released back into the aquarium water even as the media reaches its exhaustion point.\u003c\/p\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eHigh Binding Capacity:\u003c\/b\u003e Removes up to \u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"37\"\u003e15,000 mg\u003c\/b\u003e of phosphate and \u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"64\"\u003e10,000 mg\u003c\/b\u003e of silicate per kilogram in marine environments.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eHeavy Metal Removal:\u003c\/b\u003e Effectively binds up to \u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"45\"\u003e8,000 mg\u003c\/b\u003e of heavy metals (like copper) per kilogram, acting as a safeguard against toxic accumulations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eMassive Surface Area:\u003c\/b\u003e With a surface area of \u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"45\"\u003e230 m²\/g\u003c\/b\u003e, Phos Stop provides maximum contact time for efficient nutrient adsorption.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eStability:\u003c\/b\u003e The iron-based structure is chemically stable and ideal for the high-flow, high-purity requirements of reef systems.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-path-to-node=\"7\"\u003e\n\u003ch3 data-path-to-node=\"8\"\u003e\u003cb data-path-to-node=\"8\" data-index-in-node=\"0\"\u003eApplication \u0026amp; Dosage\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"9\"\u003eTo maintain optimal reef health, phosphate should be kept between \u003cb data-path-to-node=\"9\" data-index-in-node=\"66\"\u003e0.03–0.1 mg\/l (ppm)\u003c\/b\u003e and silicate below \u003cb data-path-to-node=\"9\" data-index-in-node=\"105\"\u003e0.1 mg\/l (ppm)\u003c\/b\u003e.\u003c\/p\u003e\n\u003cul data-path-to-node=\"10\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,0,0\"\u003e\u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"0\"\u003eStandard Dosage:\u003c\/b\u003e Use \u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"21\"\u003e50–150 ml (approx. 30–90 g)\u003c\/b\u003e per \u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"53\"\u003e100 liters (26 gal)\u003c\/b\u003e of aquarium water.
