What a wonderful forum! I am a new reader and am so impressed.

I have the same issue with a high CYA, chlorine at 0, and ph at 7.8 and just have a couple additional questions:

1) I can't afford to drain my pool right now to get the CYA down so is there a temporary fix for the summer that will make the pool swimmable? What is the downside to frequently adding a lot of bleach to get the chlorine up temporarily?

2) are there any real health dangers to swimming with high CYA and a ph of 7.8 or is it just more of a risk for algae?

3) what are the biggest risks of draining the pool myself if i decide to go that route?

4) just for kicks - how dangerous is it to swim with chlorine at 0? if no one uses the pool but me is this a health issue?
