After adding more acid, PH dropped to 7.2. Alk didn't budge though

Oh well, I have a vinyl liner, so not going to worry about it unless it causes a problem down the line. Water looks and feels fantastic.

Another thing I noticed, when the PH was high, the liner had a somewhat slick feel to it. Not like a biomass film, just a bit slippery.

Now that the PH is down, liner feels squeaky clean Whether that's a function of PH or bleach being more effective at lower PH, I like it
