My first SLAM....and still SLAM-ing

[cata]

@chiefwej .... My this morning test results:
FC-9
CC-0
PH-7.5
TA-80
CH-525
CYA-70
Salt-3300
CSI is -0.08 (balanced)
So I can see now after paying attention to CSI section on the poolmath that 525 will be just fine and give me a "balanced" on CSI.
I just do not have a source of water that will lower my CH. I already replaced 30% and my CH did not drop much due to my replacing source has high CH.
I guess I can live with high CH as long as CSI shows balanced.
Now I need to get rid of calcium scale... ... is it acid wash with no draining a good option or is there something better?

It depends on how much scale and how patient you are. I had a modest amount of scale and it went away over time by me just keeping a CSI around -0.15 to -0.2. But it takes a long time. My neighbor had a lot of scale and had the pool drained and acid washed. Acid wash will quickly rid you of scale, but it will also shorten the life of your plaster.

Thanks....I think I will take the long road to getting rid of scale with CSI levels...no rush
