If that is the shock level for your CYA ... Yes.

Follow the SLAM until you pass the 3 criteria. A week is a long time so yes the FC can drop from 30 to 12 ... that would likely happen in 2 days.

When you say large chlorine level drops can happen in 1-2 days, is it normal to lose that much if there pool chemicals are perfect? or does it only drop 1ppm in that case. If i have a 22 FC and the water is fine is it safe to assume that the next day it should be 21? Assuming no chlorine generator is on and the stabilizer is 60-80. For example. Yesterday, FC was 25 and today is 22 the next are there still contaminates in the water killing the chlorine? I have been constantly bring this up to shock levels for 13 days now.

Thanks!

The CYA protects a % of the FC from the sun. For example, at a CYA of 50ppm, over a sunny day you may lose 50% of your FC to the sun. At a higher CYA, the percent would be a little less.

During the OCLT, you should not lose more than 1ppm to pass because there are no losses to the sun.
