What needs to be balanced before I SLAM?


Jun 2, 2018
I bought a TF100 test kit so I could SLAM to kill algae. My CYA was way too high though so I had drain and refill approximately 70% of my pool. Yes, I still have algae.

My water is mostly fresh and untreated now.

What do I need to balance, if anything, before I SLAM?

I will retest my CYA first after the pump runs for awhile.
