Hello - We live in the midwest, using pool seven months out of the year, and have been dealing with a cloudy pool and very high levels of ammonia (>8ppm with 8 highest measurement goes) since late last summer. No, we do not know the source of the ammonia (no kids in water, few adults, no fertilizer on lawn, electronic pool cover - perhaps it’s coming from the 1 1/2 year old sand filter? -we are getting a new fiberglass w/glass filter). After doing everything “our pool guy” and a leading swimming pool supply company have said (often in dichotomy) with no success, we came to your site and did the “chemgeek superchlorination method” using 24 gallons of liquid chlorine in total. We finally got the water pretty clear, then closed the pool only to find it cloudy again 5 days after the close (in Oct, 2016). Perhaps we didn’t actually achieve breakpoint as we thought. We are getting ready to open the pool again and are wondering how to approach getting rid of the ammonia and how to open the pool and in what order. Our pool guy thinks we need to open with 6 lbs of non-chlorine shock. Will this eliminate the ammonia pretty permanently? As instructed, we just performed a 12-hour water transfusion (without pump running) which did nothing except lower TDS from 1000 to 700. Any help is always appreciated. (FC=0, TC=0, CH=220, CYA=0, TA=175-240, pH=7.4, TDS=700, Pho=800).
