I patched my leak (here: Maybe a leak?), and was away for a few days so I couldn't check levels, etc. (but the patch held so that's great). I ran my battery of tests this morning and got the following results (27.4k SWG pool):
pH: 8.2 (off bc of FC?) (Acid demand test 2 drops to 7.5)
TA: 100 (turned on 4th drop of 10ml sample)
CH: 50ppm (turned on 2nd drop in 10 ml sample)
Salt: SWG shows 3200 ppm, Aquacheck test strip showed 2390 ppm)
My salt and CYA had been high but the leak apparently fixed that (blessing in disguise). ? Should I drop my pH (adding 1-1.5 qt Muriatic Acid) then SLAM?
Also I'm wondering about return fittings, differences in diameter, type, positioning, etc. There doesn't seem to be a lot of info on this.
