We will be installing a vinyl IGP with a SWG, and have the opportunity to buy at a good price a Hydropool 395 self-cleaning hot tub which uses "bromine". Are they compatible? Will we have issues trying to regulate our pool's SWG if we and the kids keep intermixing the water from the two (jumping out of one, and into the other constantly)? Or can we damage the hot tub if salt water gets into its system? Do we need to shower off each time we go from one to the other (this may be a nuissance)?
