i have a genesis bromine generator .it does an great job maintaining my tub the cost of bromide is about $80 for the year .it is a little slow in making enough bromine during heavy usage especially if you want to use it again within 8hrs.at those times i supplement it with mps.because of this i recommend tying it in with a circ pump so it can work 24/7 i also find it pushes my ph up to about 7.9-8.0 this may just be my water even though my water is soft and starts off with low ta and ph.i keep my ta between 80-110, hardness 100-150 ppm.after a year i looked at my heater and plumbing with no indications of any scaling or pitting.it took 13 mths to build up 1500ppm. of tds above my initial fill at which time i changed my water.even then the water felt great ,clear and no issues with foam.they are a bit pricey to add to a tub .a little more reasonable when offered at the time of tub purchase.as they sell more in the industry hopefully the prices will drop.there's really not a whole lot to them. regards J.C.
