Shock question

Brushing will definitely help especially in areas of poor circulation.

OK, tomorrow I will do some serious brushing.
I am afraid to try to remove the underwater light. There was a leak there which I had to pay a leak detector specialist to fix. I would not know how to put it back in without starting the leak.

You may want to remove or access anything that has water behind it, (like a light) and clean. I had a similar experience to yours last year, which ended when I removed my light, cleaned the niche and left it all exposed during the superchlorination process.

Are you saying that some algea left alive somewhere, like behind a light, can reinfect the pool even then you stay at the recommended normal chlorine level? I thought that algea spoors afe always blowing into the pool and the normal chlorine level is supposed to keep them from growing. There must be something I don't understand.

The light itself is not the seal. The light sits in a sealed bucket. At least that's how mine is... my light is entirely out right now. I can't find something that matches my Smithsonian-worthy light.
