SLAM procedure question

[motorhead_ck]

Hey all, new to the forum but long time lurker. Been using pool math and the big pf pro test kit for a few years no issues but opening this year is a little different. SLAMED opening with very little algae, within a day was Crystal clear, 2 days for 0 CC. Pool water has TC 21 but my TC seems to be falling only .5 per day since it's cool. I think it's been 36 hours since I last added chlorine and it came down from 21.5 Now the real question is do I need my pump on this whole time until TC drops to it's proper level or can I kill the pump and run it's normal 10 hour cycle?

If you passed all three criteria of the SLAM then you can revert to business as usual. The FC will gradually creep down each day. Just remember to stay on the hot side of your CYA reading to remain safe.

Make sure you explain the differences between TC, FC, and CC. TC isn’t generally useful so I assume you mean FC?

Thank you all for the replies, Bperry you are correct I got them backwards it was free chlorine. Was doing the tf pro chlorine drop test. Had a brain fart.
