No kidding...your CYA is 8? I'm wondering how you can even measure that -- usually it's in increments of 10. It needs to be in the 30-40 range in order for your chlorine to hold in the pool and do its job. Right now, with that 90 degree heat, you probably lose half your chlorine every dayto sunlight, before it can kill the bad stuff. Some is doing its thing, though -- the CC of 4 shows that. Run some pucksand keep using bleach.

The pucks will raise your CYA automatically and will keep a continuous dose of chlorine going into the pool. It'll help you keep caught up without pouring gallons of bleach into an unstabilized pool.

Both the pucks and the bleach will lower your Ph a bit on their own, as well. I'd work on clearing the water before worrying too much about Ph. Yours is high, but not out of sight. Plus, you may plummet into acidic range quickly by chlorinating so heavily.

In any case, it's best to move slowly and handle as few variables at a time as possible.
