Thanks for the replies. I think the floater sounds like the best alternative if the SWG dies. I'd rather not have to bump the chlorine up with the SWG "just in case" every time I leave.

I didn't see anyone comment on the safety of have a SWG and puck feeder in the same line. Though I don't think I will do that now, I'd still be interested to know if doing so would be a safety issue.
