Water did not get into the ozonator. I had two check valves and made a Hartford loop. I've read quite a bit on ozone lately, and apparently the gooey substance in the line is a normal by-product of the system. I had a 250mg/hr unit in there, which is probably why this all happened in a year. I'm looking at putting in a 50mg/hr unit, like the Del MCD-50. I don't use the spa heavily and, from what I've read, what I had in there was way overkill. In my searching, I've seen various "ozone mixing chambers" which look like they replace the stock venturi/injector and make the whole process more efficient. If anyone has an opinion on this please let me know. If they are recommended, any model suggestions? Thanks again. Advice from professionals is invaluable!

This ozone unit has been used about four times a day at 3 hours each use. If I had known that I would need to spend $250/year I might have rethought the ozone unit. Although, I suspect the partially clogged line may have contributed to its demise. I was told that pillows etc. would probably be compromised, but they have faired pretty well. Perhaps I should get a smaller unit? The Cameo is a 450 gallon spa. Considering all the facts: 1) Is there a more ozone-resistance tubing and/or check valve that can be purchased? 2) Anyone aware of a repair kit for this unit? 3) Should I consider something less expensive, like a Delzone MCD-50? Thanks for the replies, Dave

Hi all. New to the forum and hoping someone recognizes this weird issue. I have a 2006 Sundance Cameo that I purchased from a friend a little over a year ago. When I got it, there was no ozone installed. The venturi and plumbing were all there, but they were blocked off. I purchased and installed a 6473-125 250mg/h CD ozone unit, because I was "told" it was the most reliable and the highest output. I mounted it as high as I could (about 2" below water line) and followed the installation instructions (looping the tubing, etc.). I tested it, and when the ozone symbol appeared in the display, I could see lots of small bubbles coming from the discharge area in the spa. Fast forward to 9 months later. I was cleaning the spa and happened to look at the display. The ozone symbol would come on, then go off, sporadically. I could see bubbles, but not nearly what it was when installed. I took the side panels off the spa, and found that the tube from the CD unit to the venturi was very hard. I realize that this will probably happen over time, but it was VERY stiff. Also, the outside of just that tube was sticky. About 12" up from the CD unit inside the tube there was what looks like a bunch of white precipitation in one section. Closer to the venturi, there was a small amount of a semi-transparent viscous fluid in one of the loops I made to stop water from coming back to the unit. In one of the other loops there was a small amount of water. The outside of the tube is mysteriously sticky along most of its length. So I disassembled the CD unit to see if there was a smoking gun. The output nipple was almost completely blocked by a white powder. I was told this unit is not repairable. Oddly, the CD unit inside the ozonator box has what looks like the identical parts to the replacement kit for the Delzone MCD-50. They could be different, who knows. I paid over $250 for this unit, and was told the life expectancy was 3-5 yrs. Seeing all this other weird stuff going on makes me think something contributed to its demise, and should be addressed before any replacement. Sorry for the long post, just want to figure this if any expert here has an explanation! Thanks for your time, Dave
