37000 gal in ground vinyl lined 1 hp pump with cartridge filter
No chlorine so I didn't test for total/free The pool store is closed so I can't get chlorine till tomorrow
CYA off scale I filled the TF100 tube to the with the proper mixture and could see all the way to the top. I don't understand this. It was perferct at the end of the season. I don't use stabilized chlorine.
The water is clear and looks great. I don't have any trustable pool stores in this small town. I am hoping somebody here can help me get started. I will get chlorine tomorrow and shock tomorrow night so I can get some better chlorine numbers then. Could it be that the chlorine is affecting the CYA numbers?
Thanks ahead of time for helping. The smart people here bailed me out last summer when I fought an algae problem and the pool stores were taking me for a hundered bucks a week on chemicals that I didn't need.
I read a little more here and realized that the scale on the CYA tube is inverse. I had it backwars which makes complete sense now. How much cyanuric acid do you think I should start with?
