Cannot raise CYA

Also, has the pool been losing water more than normal (i.e. leak)?

Nope. Topped off a week ago tomorrow and I'd say it's dropped maybe an inch or two and much of that is due to kids splashing around.

Let me ask PoolDoc to see if he sees anything I am missing.

Something else I thought I'd add, I'm in Las Vegas and my water temp is in the high 80s to mid 90's (or at least that's what my HTH therm. says), could that be causing an challenges?

[Watermom]

I wouldn't think so. My pool temps typically range from mid80s to sometimes low 90s after a long stretch of hot temps that we often have. (Usually 85-90 most of the time.)

There are only a couple of ways that you can lose CYA:

Water loss due to splash out or a leak

CYA degradation due to high chlorine or bacteria

Water loss is much more common reason than degradation but if you let the FC drop for a long period of time, that can cause bacteria to proliferate and then CYA degradation can happen.

How would I know if I have bacteria? I don't see anything in the pool, water is crystal clear.

Is the consensus that I should leave the additional HTH conditioner out for now?

Definitely do not add anymore at this time. I have asked Ben to pop in here and give use opinion. Hopefully, he'll be around to do so this evening.
