Here's the deal. A week and a half ago, my pool looked great. A week ago, started seeing some algae. No big deal, I've been there before. Shock, Algaecide, Flock, Vac to waste.
Had the water tested at the pool store (I was out of CYA reagent for my TFT100 kit).
Results:
FC - .1
TC - .2
CC - .1
pH - 7.5
Hardness - 60
Alkalinity - 100
CYA - 35
So, I bought bleach and shock and algaecide and prepared to hit it hard.
Here we are today (one week after those results). My pool will NOT hold FC even after being hit with 20 lbs of shock, and 16 (121 oz bottles) of 8% bleach!
Pool is still as green as before, maybe worse. Heavy rain here every day for the last two weeks, BTW.
Today's results:
FC - 0
TC - 1.1
CC - 1.1
pH - 7.3
Hardness - 50
Alkalinity - 70
CYA - 100
Plenty of stabilizer now! I realize that as CYA gets higher, it becomes more difficult to reach shock levels but it should at least hold some FC shouldn't it?
Any suggestions appreciated.
BTW, it's a salt water pool but the cell is dead so I've been converting it over to straight chlorine.
