Phosphates eating up my chlorine?

[wposton84]

It's approx. 25K gallons.

Any idea at what Calcium level I would begin to notice the water turning milky? (It's a vinyl liner pool, BTW)

Of COURSE Jan rocks! (just ask her kids! )

Somewhere between 400 and 500ppm your water could go milky--if your T/A is high and your pH is a bit high.

If, for example, your T/A hits 200ppm and your CH hits 500ppm, your odds of a milky pool are good. But if your T/A is 180ppm and your CH is 400ppm, you will probably be OK.


If, however, your CH is in the 0 to 400 ppm range and your T/A is 125ppm or below, your odds of a cloudy pool from calcium is extremely low....any cloud is something else.

But with a T/A of 130 and CH of 230 you have NOTHING to worry about!
