I'm planning on getting a test kit, but in the meantime I had the pool store test the water:
Total chlorine: 0.4
Free chlorine: 0.0
Calcium Hardness: 75
Pool is 14,000 gallons, sand filter, above ground.
I've read the pool school, but would still like opinions on this. I will be using liquid chlorine 12.5%.
The pump is up and running. I'm assuming it's best to add CYA and then SLAM once the CYA level is up? Or should I just start hitting it?
