OK,
18,500 gal AGP vinyl liner, buried 3ft in ground.
2.0 hp pump, Hayward 1.7 sand filter
All items brand new install last July, used BBB and was beautiful until we failed to get cover on before algae took over at end of season.
We have cleared out all leaves, sticks, gook. Although I know that there are a few rocks, toys, etc. on the bottom that I can feel with vacumm/screen, but nothing organic I believe. We have been vacumming 2/day, backflushing more than needed (ever couple hours just to be sure). And when we vacumm, we need to backflush at least once.
The pool is making very slow progress and 5 days ago we added ecoklean, Maintain (DE filter replacement material) to try and help the function of the sand filter after reading up on that in the forums. (directions called for 8 cups for the 1.7sqft filtration area of our filter)
FC has been holding at 15 overnight for a few nights now. Only losing FC ( 7-8ppm) during the day as it has been sunny.
These are my test as of 15 min ago:
FC=12.5 (which I will now add 96oz and bring up to 15 shock level)
CC= .6
PH = 7.3
TA = 100
CH= 50
CYA = 30
Just the cloudiness is killing me. I told my husband about the POP (patience needed) and he is almost there yet, but if there is any way to speed it up we may try it. But talk me off the ledge of FLOC...
Thank you guys in advance and I hope you are having a great Memorial day
