Really confused on cause of haze

I would go to 20 or 25 ppms with the chlorine. Sometimes you just need a higher level of chlorine to reach "break point" and since you are on the border with "cya about 50", then the higher level just might do the trick.


Stabilizer . . . . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . . . 8 ppm . . . . . 15 ppm . . .. 25 ppm

by keeping it at 15, you may be holding what you are fighting, but never getting ahead of it. Try bringing up the chlorine, and see if the clarity changes. The ph could be off a little, but it wouldn't make your water cloud. Sometimes you need to keep the chlorine level high for a week to break down what is in the water.

It also depends what kind of sequestering agent you used - if there are a lot of metals in the water, it could cause cloudiness. The high chlorine levels will break it down and then it will filter out.
