Any users of these products? How do you like them. I noticed the sticky on Water Chemistry mentioned using a Spa Frog floating system.

Does anyone use this and add Di-Clor manually? We are starting up a hot tub soon. From what I have read so far, Di-Clor seems to be favored more than bromine. This spa may get used infrequently also. From what I have read, the Spa Frog or Nature 2 seems to be a good option and will allow a lower level of clorine and has water softening beneifts as well.

What are peoples actual experiences, would you recommend going this way, once the water is balanced?

I forgot to mention, the spa has an ozonator, but it is old and and bulbs are not available. Also the method of injection is via an injector at a jet air tube, instead of the better injectors in the plumbing. We won't have ozone at start up and may not for a while.

Does anyone have any experience with using the Mineral stabilizers with only MPS. I have noticed on the Spa frog and Nature 2 web site that they say you can use just MPS and their product and no sanitizer. What are others thoughts on this?
