Great - so I emptied about 1/3 of my pool water (didn't want to risk my liner by emptying more than that - over time it has pulled away from the sides in a couple places). My CYA is still 100 so it must have been higher than that before. :-(

I turned off my chlorinator and started dumping in the bleach. How many hours must I wait to check my chlorine levels again? I want to keep it at 25 so the water clears quicker.

Thinking a lot of people are reading your site - big stores are running low on bleach! Thanks!
