Time between SLAM and test

[JeffRH]

When adding liquid chlorine for a SLAM, does the 10 minute rule referenced in this article apply for how long to wait until testing Cl levels? Or is advisable to wait longer?

How long to wait between adding pool chemicals

The wait times between adding pool chemicals is usually around 10 minutes each, as that is also sufficient time for the chemicals to mix in the water.

Wait a bit longer to test........closer to 30 min

Jeff, I would like to clarify. That article, referencing 10 minutes, is the time recommend for chemicals to mix before adding other chemicals and/or swimming. Basically saying that 10 minutes is long enough to safety mix and get out of the way for swimmers. It's not for re-testing your levels. If you add certain chemicals, you will have to wait longer (perhaps 1-2 hrs or more) to re-test for a new reading. The only exception I can think of is for people who are assumed to have ammonia in the water which requires a very aggressive (initial) chlorinating process of testing FC in 10-minute intervals. But for the normal situation, that' doesn't apply.

Does that make sense?
