tydy bowl blue water

[MessPool]

Here are my test results: Free & Avail Chor 3.0, Alk 126, PH 7.1, Calcium Hardness 207, CYA 30, zero copper & iron, Total dissolved Solids 820 Saturation index -0.36. Just for the record my liner is blue, but the water is, as a rule, clear. The sand was not changed, but it was cleaned. I keep 3 chor sticks in the skimmers. I'll get a pic this afternoon. One other item that may be of interest. This pool dealer is new. Years of experience installing, but I'm not sure about water analysis, however it is a computerized test. 'Poolife Brand" And come to think of it, the Algaecide was purple. Thanks in advance for your help.
