You caught us in a major transitional period, where we were dealing both with a bunch of spammers (up to 20 bogus registrations per day!) and a move to new software and a new server.

I'll move your thread to the SWCG forum -- maybe someone has done something similar.

But I think you are asking for a lot of trouble with this. First, it's going to be hard, and maybe impossible, to size an SWCG so that it will have chlorine delivery rates appropriate for both a spa and a pool. Second, the control and timer mechanism internal to the SWCG's I've seen aren't going to synchronize well with your pool/spa switch over.
