Tested my water and results are FC 5, PH 7.6, TA 90, CYA 70, CH 700, Salt 3400, Borate 30. Water looks Great. Should I be concerned with a high CH. I am going to work on lowering TA to 80 with MA. Also I would like to thank this forum for guiding me on testimg my borates using the drop test method with the reagents and supplies listed. It worked like a charm using the speed stirrer.
