I have been battling a cloudy pool problem for weeks now. Had a bad mustard algae break out three weeks ago. Finally killed (had to use an entire bottle of Algamacine (sp) X)
I have read the write up here on shocking your pool and have used the pool calculator to determine how much shock to put in but this seems very extreme.
The readings I started off with.
FC - .5
PH - 7.3
TA - 110
CH - 280
CYA - 90
So the first day I put in 12 lbs of 68% shock... reading next afternoon... barely .5 (reading from pool store)
Next day add another 12 lbs of 73% shock... reading that afternoon... .5 (this is from my own testing with my TF 100 kit that showed up via Fed Ex yesterday).
This seems nuts to me... 24 lbs in 48 hours and NOTHING! What am I doing wrong here? What else should I be doing?
Background... pool is 20x40 vinyl liner, 1 1/2 HP pump running 12 hours per day, Compu pool SWG 48 set on 100%, Hayward 425 cartridge filter (brand new this year). Water temp is about 85 degrees.
Any help is appreciated... never had this problem in three years of owning the pool!
