1. There must be NO live algae when testing for phosphates.
Live algae holds phosphates "in" so the phosphate reading will be low. If all algae is dead you will have a correct reading.

2. Chlorine must be under 5ppm before testing for phosphates.
If chlorine is above 5ppm it will strip the reagent on the test strip giving an inaccurate reading

Phosphate Test Kit

Excessive phosphates levels can contribute to recurring algae growth. Phosphates are introduced into pool water from soaps, outside contamination and deck/change room cleaning products. Test weekly or monthly to accuratly dose PhosFree.

PhosFree Commercial

Phosphate levels should be maintained under 500 ppb. Phosphates feed algae growth, excessive phosphates in pool water will lead to recurring algae growth issues. PHOSfree is a lanthanum floc. When added to your skimmer, a thin coating of PHOSfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to very low levels.
