I've shocked my salt water pool with dichlor to 22 for 3 days. All mustard algae is gone and FC seem to be holding at less than 0.5 ppm overnight.
Here's my results:
It's now been two days since my end of shock and I notice the FC levels appear to be dropping about 5ppm per day as I am NOT adding any chlorine (thru SWG or dichlor) to get it back to normal levels.
Here's the simple question ... what is a safe level of chlorine (FC) to let my children swim in the pool again?
Sorry, but such a simple question and I could not find an answer with the search.
(Perhaps someone should post a safe swim level in a sticky note somewhere so anyone can look this up.)
