I started the season late, drain and fill due to new tile that I installed. Everything looks great, but the water is just slightly cloudy - i can see the main drain fine, but it just isn't crystal clear.
My fill water is always high alkalinity so i spend every year working to get TA down, and I am making progress. Latest numbers are:
PH 7.6
Free Cl 10 ppm
TA 130
CH 250
Cya 60
SWG
Yes the chlorine is high as I thought my CYA was closer to 100 - have a terrible time reading the taylor kit - does the dot have to get hidden? what does just disappear meant, etc. So I got the larger Blue Devil test/kit and it tells me 60. I added CYA when i opened the pool, and the math told me that it should be around 70 - but my pool is not a solid rectangle so I have always taken a swag at water volume (20-22K gals - 16 x 32 with some bumps and 3.5 to 6.5 feet deep) - the blue devil test matches the pounds i added.
Anyway, the chlorine level has been stable, and I need to bring it down some, but every year i run it at 5-6 and wind up dealing with having to SLAM it, so i shocked it when opening and lowered SWG to 50% to maintain.
Any suggestions on what to check next? CC shows zero, so to me that indicates i don't have to do an overnight test.
