Perfect Corals Rapid Phosphate Reducer — Liquid Lanthanum Chloride Treatment
Transform Your Tank with Fast, Precise Phosphate Control
Looking for a reliable way to bring stubborn phosphate levels back in line before they stress your corals or fuel nuisance algae growth? Elevated phosphates are one of the most common — and most damaging — imbalances in a reef tank, and a product that acts fast can make a real difference. Perfect Corals' Rapid Phosphate Reducer is a professional-grade tool for advanced reefers who need targeted correction, not gradual guesswork.
This highly concentrated lanthanum chloride solution binds phosphate on contact, pulling it out of the water column quickly and efficiently. At a max dose of just 2.5 mL per 20 gallons daily, a little goes a long way — which is exactly what you want from a potent reef chemistry additive. Because it works fast, precision matters: always calculate your dose using the included formula, test phosphate levels at the 24-hour mark, and monitor alkalinity throughout treatment, since rapid phosphate shifts can affect your tank's overall chemistry balance. This product is dosed via protein skimmer intake, filter sock, or mechanical filtration only — never directly into the display tank — making it best suited for aquarists who are comfortable with deliberate, measured dosing practices.
