Hello all. Just opened up the pool for this year and will be using these methods now. Was using pucks before but will be switching to bleach. Measures CYA a few days ago and it was 130. Since I am just getting started for the year, I figured I might as well do a partial drain and try to fix it. So I let out about 3/4 and refilled today. Here are new readings. FC was very high before refill.
Cya 70 (ish?)
I was surprised to see chlorine was so high. I still have some pucks in the chlorinator which I guess I will let finish off. I live in New Mexico, lots of sunlight, so I think the new Cya level, while high, is still acceptable?
I added a bit of borax to try to get the PH to 7.5, as recommended by the pool calculator. How do these numbers seem to you guys? I did not have time to check the CC yet. Water looks great. Another question I have is, using only bleach from A big jumbo box store, how much can I expect to add on a 1-2 day basis? Just a few cups? Any other advice would be greatly appreciated.
