Starve algae by removing its primary food source. Calculate exact Lanthanum doses to clear phosphate 'fuel' from your pool.

Quick Conclusion
For every 1,000 ppb of phosphates, use 5 fl oz of standard strength remover per 10,000 gallons. Eliminating phosphates (algae food) prevents mustard and green algae from taking root.

Technical Comparison

Phosphate Level Risk Profile Action Required
0 - 100 ppb Excellent None / Maintenance
100 - 300 ppb Low Risk Monitor Monthly
300 - 1000 ppb Moderate Risk Optional Treatment
1000+ ppb High Risk Remover Recommended

Actionable Steps

Pro-Tip

If your pool turns milky white after treatment, don't panic. This means the chemical is working. Run the pump 24/7 until the water is crystal clear.
