Question:. Is the "dirt" looking stuff on pool floor, dead/live algae? or dirt?. I live in a windy desert climate. Not sure if I just need to vacuum daily? I switched to the BBB system about 4 weeks ago. My water is clear as can be.

16x32 AG intex, little over 14,000 gal. The "dirt" gathers mostly at the seam lines of the pool). Water hardness 500+, FC 3,TC 3, ALK 80, PH somewhere between 7.4 -7.8 (I can't tell cause the colors do not match up great) But I can tell all levels starting to decrease and its time to add my bleach soon. CYA 30-50 but those colors are starting to "lighten up" Do I need to add stablizer? and what type of times (hours) am I looking at, inbetween adding, when adding different products? (i.e. B, B, and B) I read in the forum that stablizer takes days to register. With temperatures changing, does this also affect the chemistry?
