OK, before I get blasted by the Leslie's Pool comments, let me start by saying lesson learned and flames accepted.
I recently restarted my pool after having it completely stripped down and replastered, replumbed, etc etc. After the first week, I noticed that the combined chlorine (CC) values were high while the free chlorine (FC) values were nearly undetectable. I was going to shock the pool and was convinced that I should use a product "Leslies Fresh and Clear". I had never used this before and was told that because my CC values were so high, the Fresh and Clear would not introduce additional chlorine into the pool but, because it was an oxidizer, it would release the combined chlorine. WRONG
I did a great deal of reading after dosing the pool with the monopersulfate (MSP) and realizing that the CC values had actually increased and my ORP probe was reading very high also. Found a great article from Taylor talking about "Shock Interference" and the fact the MSP would interfere with DPT CC readings unless an MSP neutralizing reagent was used in the test. Good for the DPT test, not the ORP readings. The Leslies employees did not know that MSP would interfere with the test and they dont stock the MSP neutraizing agent.
So my question is, does anyone know how long it takes for the MSP to be eliminated from the water naturally or is there something that I must use to neutralize it?
Thanks in advance.
