Basically, I have a SWG. My water test on 5/26 was
I added 2 Quart of 14.5% acid (kem-tek hydrogen chloride) into the pool. I turned off SWG and solar panel. Added 1/2 qtz at a time (mixed with a bucket of water). Ran the pump for 5 hours, and next day I check PH only drop to 7.8. My target was 7.2.
Does it take so much acid to lower the PH? even though I poured in 2 quart of 14.5% acid, it only lowered it by .4 ph .
Do I need to add acid every week for a SWG system?
