Usually the CC is low if you are able to pass the OCLT and the water looks clear. If you pass, let the FC start to drop. It is safe to swim up to shock FC level.
What page said that?The page said nothing is really accurate during slam so I'm just curious.
There is no point in testing the PH until the FC level comes down below 10. Until then the high FC level will throw off the PH test results.

I am saying you need to be able to measure the CYA level. Depending on the kit you got, the minimum is 20 or 30ppm.
For an indoor pool you can have any level of CYA, the required FC ratio is the same. There is just no advantage to keeping it higher that the minimum you can measure.
