The signature profile will allow us at a glance to remember your pool data without having to search back in the thread for the info. The bigwig experts really don't have time to do that. Maybe we could have caught the "somehow connected" spa issue earlier! Notice how it should contain volume, equipment details, other relevant details like attached spa with overflow into pool, and your test kits.

Wilco, what's happening?

Success is whats happened. After shocking with a myriad of bottles of chlorox and keeping cl above 20 for several days, I let it drift down slowly and now have had stable levels in the 5-7 range by adding a gallon about every other day or every third. Ph started drifting up a bit last few days so added a little acid. Looks great, no sign of anything wrong.
Starting to cool into the 60s here at night so kids are not as eager to swim with cooler water temp. Don't really want to consider a cover as I have an oddly shaped pool.

Woot! Great news! Kudos on your persistency; hope you get some warm temps to enjoy the rewards!

Glad you've had some success.

One caution for future reference: we've advised store-brand bleach for years, to help pool owners escape the confusion of the multiple 'flavors' of Clorox bleach. But now it turns out Walmart is adding 'flavors'!

So, here's the key: ONLY purchase bleach that shows "8.25% sodium hypochlorite".

No %? No purchase! "Bleach" without a % can be 1% or less!

So noted. Actually I was getting 3 packs of Clorox at Costco for $8 each, better than walmart generic, and maybe a little more reliable strength-wise.
Now that cl levels are stable (5-7) I am noticing pH is wanting to creep up. I've added acid twice in a week. Before, it seemed like my pool water would naturally drift lower in ph, and in was adding the borax. Could be cooler temps at night. tA is 110, not much change. Will monitor for a while, but I was under the impression acid use would be rarer.

Perusing other threads I noticed it mentioned that aeration can raise pH. I have had the water feature on 8 hrs/day when pump is on ( two lion head spouts). Could that do it? The timing fits.
