I have severe black dust on pool floor. Tried vacuuming several times, but it just muddy up the water and comes back once the filter is turned off and the water settles down again. We had strong wind and rain during the past several weeks and I thought it must be dirt or whatever that got deposited during the storm. But now I am suspecting if it's algae or something else. I cant really vacuum it because if I am not gentle enough, it will easily muddy up the water that I can't see the bottom anymore.
These are my test results.
FC - 2ppm (added liquid chlorine last night and ran pump for 6 hours)
PH - 7.8 ppm
TA - 80ppm
CYA - 30ppm
