I've searched and read, but haven't found a specific answer...
One of the criteria for successful end of SLAM is crystal clear water. Is this just an empirical observation (i.e. do it because it works), or is there some reasoning/understanding behind it? In other words, if all the algae is dead (presumably evidenced by passing OCLT and having minimal CC), why is it necessary to maintain shock levels while waiting on filtration?
Does the dead algae provide nutrition for new algae or for other life forms, thus encouraging a new outbreak in the water? Is the thought perhaps that cloudy water keeps the pool owner from accurately scrubbing off all remaining (live) algae spots on the liner? Is there some other reason?
Those of us with crappy filtration systems (seasonal pool owners using out-of-the-box equipment for pumping/filtration) would like to know.
Also, a related question... SLAM protocol calls for keeping pump on 24/7. However, the only way I can get our pool clear after killing algae (working with a woefully inadequate filter, for the moment anyway) is to turn the pump off, wait for the assorted fine junk to settle (requires hours without circulation), and then vacuum to waste (which is accomplished by siphoning the stuff at the bottom overboard). Is that period without circulation a major problem?
