New to TFP and seeking some advice. We have a 19,300 AG pool installed last year. We did not cover the pool over the winter. Pool is cleaned up and now starting to balance the water. Currently having Leslie's Pool Store do our water testing while we wait on our test kit to come in. Ordering the Taylor K-2006C. Current test results are 0 FAC, 0TAC, 240CH, 0CYA, 110TA, 7.4PH, 0 Copper, 0 Iron, 200TDS, 0 Phosphates. We have added 12 pounds of shock so far and still reading zero. Water is cloudy blue tint with a little foam. Attached is a photo took this morning. The only difference from last year and this year is we have a Pool RX in the pump basket. Any help with the chlorine reading is greatly appreciated.
