Yes, when we used pucks and dichlor, rarely added muriatic acid. The brand of OTC bleach I use is HEB, 8.25%. Older posts on TFP attempting to explain the lye amount differences, say between Clorox brand and HEB, made no sense to me. I even searched and read up on MSDS, etc of the bleaches. I tried using Clorox brand for a while, but frankly I felt it sanitized less. Clorox does not seal their bottles! If you know the answer to which OTC has less lye, I'll be happy to be informed.
Since using bleach, my pH rise has been a constant struggle. I have had mod scale on tile since I began learning the BBB. I'm a little better. Say my TA is at 70, I find the pH climbs to 8.0. I try to gently add a little acid. Bamn, my TA is now lower. That's why I add soda. Posts say acid drops TA harder than soda raises pH.
There is a spillover. Very low drop, especially now with a lot of evaporation. Am running pool 24hr at 1250rpm. When I add bleach at midnite, I run rpm higher for about 3 hrs. My pool is old construction. Two jets on south side, one on north in shallow end. There is poor circulation to the south deep end - where in the past I always got algae. North deep end has skimmer basket. Once temps got in the 90s and up, I increased to 24hr and my pool has been clear again.
Pool was re-plastered early 2000s. (On signature) There is still black algae spots, not increasing, which I plan to attempt to eradicate in the fall or winter when I can SLAM and there is less FC demand. My CC is 0 ?? I do brush with metal because of the black algae and a very coarse diamond brite plaster.
Lastly, we were told to keep the TA closer to 90-100 with diamond brite plaster by the installer. I'm just trying to keep TA above 70! Any thoughts?
