Thank you pool doc!! Your the best.....

I only use a leaf cover for the winter. I close the pool per instructions here pretty much. It always seems to turn green though. I would say I though the leaf cover lets the sun shine in all winter and thats why it turns green. I have not used the polyquat the past few yrs. Could that be it?

This yr I used some algae stuff from the pool store that was on sale. 1 gal for $10 bucks. It was light blue and you added 1/2 cup are so. I added it throughout the winter, but it did not work. Ok so I will either

a) need to get a solid cover for next yr, or
b) do what I am doing but make sure I add polyquat only. Add some periodically I would assume.

I will need to read some more here and refresh my self with pool closing. OK, well I need to think ahead for next yr and not let this happen again.

Ugg... This sounds like its going to be a carbon copy of last yrs nightmare...
