When SLAMing, how long after adding LC can I test FC?

[djdonte]

Its been years since I SLAMed. My SWG screwed me over the weekend and the water got dull. Slight cloudiness but no green yet. I had 1 FC at 60 CYA!! I lost 3FC during the OCLT. I started slamming today but either the heat messed up the LC home depot keeps outside or algae is eating my FC quickly. How long after adding can/should I test? I want to say 30 min but I forget. When I add LC, I distribute it evenly in front of each return jet.

With pump running, 30 minutes is fine. If you want to be really sure, brush the pool after adding the chlorine.

Thanks and great idea on the brushing. This is the only downside I see to salt… the high CYA makes slamming a pain.
