1.) will do - what is "oto kit"

2) I assume on recirculate?

3) I will do that as I can...I think the brand is jacuzzi on both..I found a pump+filter system online that looks very similar to mine but it's for above ground pools...not sure how much that matters.

How long do I do the bleach treatment? Also, I think I've got about 25,000 gallons if that makes any difference...

Thanks,
