I'm continuing to post updates on my other thread but I have a quick question.
We are getting close to finishing the shock process. When I get home from work, I plan to test FC and add any needed chlorine. How long do I need to wait before re-testing FC for purposes of the OCLT test? Pool School says at least 30 minutes. Is anything longer than that and dark out OK?
Once we pass the test, do we then allow FC to dissapate until it nears our target of 7 for CYA of 60 before running a new full set of tests?
