Added liquid chlorine before I checked other levels...how soon can I get accurate reading?

[kittersue]

We were in a rush today after opening our pool, and hubby dumped in 2 gallons of liquid chlorine to start shocking it before I could even whip out my test kit. How soon will I be able to get valid readings for pH, TA, CYA? The pool was relatively clear, just dirty on the bottom with some leaves and plant material. Vinyl pool, 25,000 gal.

Only pH is an issue if your FC is above 10 ppm. All others can be measured with accuracy.

Many thanks, as always, to the experts here on TFP!

Only if the FC is >10
