PhosLock

Concentrated Phosphate-Binding Solution Reef Charge PhosLock is a concentrated phosphate-binding solution for reef and marine aquaria. It binds reactive PO4 into a filterable particulate for controlled phosphate reduction when used with mechanical filtration and/or protein skimming. Use When Phosphate is testing above your target range. You want a controlled, test-guided phosphate reduction without adding organics. Your system has mechanical filtration, filter floss, a filter sock, or protein skimming available to remove the formed particulate. Directions Test PO4 before dosing. Dose near a mechanical filter or protein skimmer intake. 1 mL per 4 US gal targets up to 1.0 ppm PO4 reduction. Do not exceed 0.5 mL per 4 US gal per day. Dose gradually. Allow the water to clear, remove particulate through filtration/skimming, then re-test before dosing again. Important Caution Rapid PO4 reduction may stress sensitive livestock. If corals, clams, or other livestock react, stop dosing or reduce the dose by 50%. Use with reliable phosphate testing. Avoid large swings.
