This is our first pool. Above ground, 20,000 gal. I had too much trouble using the AquaTest-4 color strips. The salesmen highly recommended the AquaChek TruTest monitor, which they all use in the store. The pool had been covered for a couple days by the solar cover, during which time we had multiple rain storms. Upon removing the cover, "GREEN". I discovered that our chlorine canister had gone empty sometime during the week of rain. I shocked the pool with 4 gal of liquid shock. Green has disappeared but water is very cloudy blue. Tested yesterday with TruTest indicated pH was low, so I added "pH UP" according to directions. There has been no improvement today, so I retested. The TruTest monitor indicated 7.1 (pH still low) which caused me to try another test using the Hydrotool, drop method test which shows the results as 7.8 (pH high) Very frustrating; which method should I rely on to treat the water? Is it cloudy because the pH is too high, or too low? It's like a crazy 'crap shoot'. The pool stores here are using the 2 same methods I have. A neighbor stated that it may be caused by Phosphates. The pool clerk said the unless we live next to a farm area where they are fertilizing, etc. it's very unlikely to be a Phosphate issue. She didn't have the resources to check for Phosphates in the water. Seriously welcome to suggestions!
