This phosphate remover is designed to eliminate both ionic and chemically bound phosphate from your saltwater aquarium, ensuring stable calcium levels and promoting healthy coral growth. It works effectively by precipitating out phosphate and trapping it in existing filter media like wool or socks. The product includes deionized water and purified lanthanum and comes with a measuring cup for accurate dosing. Dosage should be adjusted according to the current phosphate level as indicated on the instruction label, and it is essential to use this product alongside a protein skimmer.
