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.
