Description
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.
