I drained my hot tub back in December, doing the enzyme treatment first, so when I got around to setting it back up, all I would have to do was the super clorination before getting it back up and running.
Well, I pulled the cover off last night and was very disappointed to find about 5 inches of mucky water sitting at the bottom. It was super dry and clean when I covered it. Guess water from rain/snow leaked in. There are some jets at the bottom that were emerged in the yuck. Should I fill it back up and do the enzyme stuff again before the superclorination?
Want to make sure I get everything off to a good start! Thanks.

I wouldn't bother with the enzyme stuff. Just drain the dirty water, fill with clean, and shock, and you will be good to go.

Thanks!
