The test result is
CYA around 20-30
CH around 420
TA around 90
Should I lower the ph value first and then add lot of bleach? The water is still clear now. Do I need to shock ?have not do any shocking before??
Do I need to adjust CYA level also?
How often do I need to add acid usually? I don't like to deal with the acid at all. Just add 2 cups a week ago to get it to 7.8. My nose accidentally get in some fuse. Hope I don't need to put acid quite often.
I am TX. The pool buy (which was dismissed a month ago) told me that my pool has a leak because the water level goes down a little bit too quick. The water bill is about 100 now, which is still affordable. So we may start to check this when we are able to get the water quality stable. Should we hire a company to check and repair the leakage or can we do the check and repair by ourselves?
