Directions for use: DOSAGE: 1 quart for up to 20,000 gallons* *For pools smaller than 10,000 gallons, do not exceed 16 ounces in one treatment. INITIAL HIGH-PHOSPHATE TREATMENT: 1. Clean or backwash filter. 2. Calculate the amount of product required using the dosage instructions. Pour PHOSfree MAX in the pool, distributing it over as wide an area as possible. Important: It is normal for this product to cause pool cloudiness, indicating that phosphates are being removed. The duration of the cloudiness will depend on phosphate levels and pool equipment and can sometimes last up to 48 hours. While pool water is cloudy, swimming should not occur so plan your treatment accordingly. 3. Run your filter system continuously for at least 24 hours. 4. If filter pressure increases 10 psi over normal, clean or backwash the filter. 5. After 48 hours, test the phosphate level with a phosphate test kit approved for swimming pool use. If it is needed, re-apply PHOSfree Max.

Natural Chemistry 15303NCM Phosfree Max, 32 oz.

Q: Love your phosfree product How is this different from phosfree and professional phosfree?

I like phos free for weekly maintenance. However phosphates in my pool were over 6000 after crop duster flew over several times. Phosfree Max didn’t make a dent in it. I had the best results from PR-10,000. Awesome product. I treated. twice and no more phosphates.
