CYA loss due to water evaporation...

[gtnos]

I know CYA is only lowered with water changes, but earlier as I was topping off our pool again (already losing 100-200 gallons per week due to evaporation) I began wondering, does my stabilizer stay behind when water evaporates?

or does it get left behind in the pool?

Stabilizer stays in the pool. As pool water evaporates, concentration of stabilizer in the remaining pool water goes up. As you top off, the concentration goes back down to where it was.

CYA will stay in your water, it does not evaporate out, same as your CH.
