We opened our new pool this year and everything was great and then the filter got clogged last week while out of town and pool chemistry went crazy. Now we are not getting any reading for chlorine or CYA. Both are very low. I added CYA and then Shocked and then added chlorine ganules and still nothing. Leslies pool now says to add a bunch more CYA and a few other things. Not sure why the Salt Generator is not producing?
