I just discovered my hot tub has an ozonator. The owner's manual mentioned it but the sales description did not. It explains the mystery trail of bubbles coming out of one of the floor jets.
Can ozone destroy CYA? I added enough for 20 ppm over a week ago (slow to dissolve of course) but analysis indicates none present now.
Should I add NaBr and begin using bromine as my sanitizer? I'm only filtering two hours per day. Manual says ozonator only works when low speed pumping.
I bought one of the much maligned (primarily by dealers on other discussion sites) Infinity hot tub from Costco. I have been using it for almost four months. I decided it might be worthwhile to add insulation under the tub and on the sides. The tub sits on a ground level deck a few inches above bare dirt.
There is a layer of spray on foam insulation on the back of the tub and most of the plumbing. The pump mounting is sloppy (vibration isolation pads not centered well). There is a stiff plastic sheet under the frame of the tub and pieces of plywood on the frame where the pumps or the woofer (another surprise) sit. I shoved styrofoam packing material (loose and sheets) under the plywood and over the exposed plastic sheet. I taped 1” R-4 blue wall insulation in the side panels and reattached the aluminized bubble wrap over the sides. I left the two pumps clear of added insulation out of concern for overheating them.
