Pool Pilot and shocking with potassium monopersulfate

[catnip]

The Pool Pilot manual recommends using potassium monopersulfate as a supplemental shocking agent. Is there any reason to use this versus bleach? Perhaps PoolSean can chime in if he sees this.

Edit: I just found a couple of threads that speak to this but welcome any additional advice:

Hey Chuck,
No specific reason other than the marketing in saying, never have to buy chlorine again, because Potassium Monopersulfate, "technically", is not chlorine.
You can use really any chemical that is compatible with chlorine, including chlorine. The only one I would recommend avoiding is an algaecide used for yellow algae or mustard algae, and contains sodium bromide. A salt system will react with sodium bromide and cause a problem with maintaining a chlorine residual.

Hope this helps,

I would just add that with an SWG system, especially for an outdoor pool exposed to sunlight, it is very, very unlikely you will ever need to shock your pool. You will probably never see a combined chlorine level above 0.2 ppm (the smallest measurable amount with the Taylor test) except right after a heavy bather load and even then the combined chlorine should be eliminated within 24 hours.

The only time you would probably have to shock the pool would be after an "accident" (urinary or fecal). And as Sean says, you can just use chlorine for that.

Sean and Richard, thanks for the clarification and additional info. I was reasonably sure that chlorine would work as well and your explanations confirm that.
