Hi, Received my Taylor TK-100 test kit yesterday. Anxious to use it I did all of the test earlier today (about 2 hrs ago). Here are my readings...FC- 1.5; CC- 0.5; Cal Hardness- 125; TA- 160; CYA- 40. I have a vynal liner 20,000 gal and am running a Hayward T-9 SW Cell with a newly installed after market circuit board by Optimum. So, I have raised the chlorine output to 100 (was running at 45 - and my cir bd reading was at 3200). I have some alkalinity decreaser. Should I try to get the alkalinity down first or raise the CYA level? I have a 1766 salt kit coming. Any suggestions are appreciated.
another question is could my circuit board be misreading the salt level. Around 3200 is where I have run it I past years.
