I am in Denver CO and have a 15,000 gallon fiberglass pool that was open all winter. I have an auto cover. My chlorine is around 2-4 range with the SWG at 8-15% output (3200ppm salt) and my ph is usually around 7.6. Occasionally it will go to 7.8 and a cup or so of acid will bring it back down.
Recently after a bunch of rain my ph went to 7 and chlorine to almost 0. I bumped up the SWG to 50% and added 2 cups backing soda. Neither had much impact. Eventually I added more backing soda to get to 7.3 (with more rain) and added bleach to get the chlorine to 3.
It seems the SWG is not making the impact it should and same for the backing soda which should have raised the ph much higher.
Any thoughts / help on what might be going would be appreciated.
