I am getting consistent PH drop with my 11,000 gallon above ground pool when using a solar cover. Reading the forums, it seems like this is to be expected. I see that this is from the chlorine tabs I use in the pool. I have been lazy and putting 4 or 5 tabs in my floater while closing the vent to one slot. I am guessing this is not helping my situation so it seems like the idea is to use less more often to limit the PH drop. On the same token, I am reading about different types of chlorine, using liquid, or even a SWG. A SWG may be a bit overkill for my pool but from what I have read it has the tendency to raise PH, not lower it. So one question I have is, to confirm if I am heading in the right direction here, and two is there a preferred chlorine to use with solar covers? Obviously, my most important goal is to keep the the numbers stable, but my other goals are to keep the pool warm while limiting the maintenance to a little as possible. Right now I have to turn on a big fountain to bring the PH back up without impacting my TA, which is counterproductive to using my heater and the solar cover. Any help here would be greatly appreciated.
