Switching to Bleach?

[KurtV]

Jim, I recommend that you not add bleach directly to the skimmer. When you do, relatively undiluted bleach can reach your inline chlorinator and have disasterous results (like an exploding chlorinator). I understand that this can happen even if you empty the chlorinator of pucks and is probably likely if you don't empty it.

On your pump run times, you're probably better off to split your pump runs into two or even three different segments instead of one big twelve hour stint.

Won't pouring straight Clorox into the pool and onto the vinyl liner bleach the color out of the vinyl faster.

Jim,
You can just dribble it a little bit at a time into the water while moving around the pool to make sure the bleach is diluted as you add it. Alternatively, you can pour it very slowly into a return stream which will dilute and distribute it pretty quickly.
