Got a green pool blue after over a week at SLAM levels. Took a break for a week to rebalance the TA and PH, and vacuum the bottom of the pool now that it was clear enough to see, and then started the process again.
SLAM'ed the pool for 2 more weeks, passing OCLT and reading no CC for 10 days. Also tried a DE boost to my sand filter, which didn't help. Water was still cloudy after all this, so based on advice I read elsewhere on these forums tried a little polymer clarifier to boost the efficiency of the sand filter. It helped a little, but my pool is still not the crystal clear pool I ran last year.
I don't know how old the sand in my filter is, but it's the same sand that was in the filter when I bought the house over 2 years ago. Been running at 11 psi since the DE boost, with absolutely no increase in pressure despite constant filtering. Is it time to change my sand, or is there something else I may have overlooked?
Current readings:
FC - 8
CC - 0
PH - 7.3
CYA - 50
TA - 90
CH - 200
