If algae is present, add a treatment of Lo-Chlor Pool Algaecide prior to beginning phosphate removal. Clean or backwash filters and ensure that the pool is balanced. Test pool water for phosphate levels using a test kit approved for swimming pool use. Using the chart below, measure the required quantity of Lo-Phos Max for your pool. Slowly add Lo-Phos Max directly to the pool, distributing over as wide an area as possible.

Example: Dosage rate for 10,000 gallon pool with a phosphate level of 1,000 ppb requires a 2 ounce dose.
- Immediately following the addition of Lo-Phos Max, place one Miraclear Clarifier Tab in pump basket or use 2 ounces of Miraclear Blue Liquid Clarifier per 4,000 gallons of pool water. The addition of the clarifier will help clear the cloudiness associated with phosphate removal.
- Run filtration system continuously for 24 hours. Check filter pressure regularly and backwash if necessary.
- Retest phosphate level of pool water at least 24 hours after treatment. If necessary, repeat dosage of Lo-Phos Max at weekly intervals until phosphate levels is within the acceptable range. for faster results, Lo-Phos Max can be added in 24 hour intervals.
- Test pool regularly for residual phosphate levels.
- To maintain phosphates below 125 ppb, add 1 ounce of Lo-Phos Max per 15,000 gallons of pool water weekly.
