Have a 40k gal inground chlorine pool and have run into a strange situation where I can't get the chemical levels in line. Decided to have a water analysis performed and came back as listed below. The company that did the analysis recommended draining the pool part way and refilling then bringing a new sample in. Before I do this wanted to hear thoughts from some of you on here... The strange thing we are seeing is the chlorine level test high and stays high, which we've never experienced before. Usually disipates very rapidly this time of year. Test Results: Free Chlorine: 5.4ppm Total Chlorine: 5.4ppm Combined Chloring: 0.00 PH 7.7 Hardness: 400ppm Alkalinity: 73ppm Cyanuric Acid: 125ppm
