Went to pool store to have my water tested and the results are different than mine.
Test Store My Test Kit FC 2 <.5 TC 2 <.5 PH 7.2 6.8 TA 90 50 CYA 80
The only thing done between their test and mine was I added Pool Perfect Weekly (Their suggestion) about 30 minutes before I used the test kit.
1) Did the Pool Perfect bring the readings down?
2) Should I trust my readings over the store readings?
