Unfortunately, this is the second pool season it has reared its ugly head. I have steps built into the shallow end that I can't get back into the crevices with a brush and my old fiber optic lights can't be dismantled until it's time for a liner change. So.....the winter closure allowed it to do its thing. The pool was opened April 23rd with clear water and A LOT of dirt and sediment. I vacuumed to waste, brushed, kept up SLAM and the stuff kept coming back, going from yellowish sand to a white dusty powder in the same places. Then....Memorial Day festivities put a crimp in SLAM process. Now it is mostly light yellow, but the water itself is like diamonds.
Currently:
CYA = 50 (treat it as 60)
FC has not dropped below 16.
CC= 0
pH=approximation of 7.5 (dilution method of 1 part distilled water to 1 part pool water)
TA = 115
CH = 220
Salt = 3600
I've had family members begging me to let them swim.....I considered letting the FC drop to 11, vacuum the stuff up and allow them to swim...but I wasn't sure if I should be concerned about bacteria and its friends.
