Once I get the FC back to shock level, should I turn the SWG back on? (Turned off because FC was way too high)
That the FC dropped in two hours is exactly what should be happening. It's oxidizing the organics in the water and being used up in the process. Over time the amount you need to add to get back to shock level will slowly be reduced.I added this morning then two hours later I was below shock level. Bleach is new and 8%. I;m going to shoot for a little higher than shock level.
