What to do next...

[jmagoulas]

OK so opened up the pool to a dark green color. Did a SLAM and now the pool is just cloudy. Filter running 24/7. Have to add more cholorine as it is low. My CYA is at 10 and my PH is through the roof. Off the charts. A bright pink color.

What is my next move? Up the CYA with stabilizer or lower PH with Muratic Acid?

Thanks in advance for any and all help.

Where did those test results come from? I'm not aware of one that can tell you a CYA of 10 with any accuracy...

Anyway, if you're confident in the test data, then it's ok to do both - get some CYA going in a sock on a return, and also lower pH with muriatic acid. Don't do the whole dose PoolMath tells you at once until you're dialed in closer. CYA will slightly reduce pH, so definitely use a bit less MA than it calls for.
