Works well

Ordered the HCD-55 as a replacement ozone generator for my hot tub. It did not produce any ozone light comes on nothing happens. So I thought i received a defective one so i requested a replacement. The replacement did the same thing. the light comes on but nothing happens. After looking at this unit it runs on normal 120/240 volt connections so all your hot tub controller does is turn it on or off. So I know it was on and working based on the light. I did test a little further by using a 4amp female connector so I could plug it in separate from the hot tub controller and it did the same thing. If you look at where the ozone exit is there is an intake right next to it and it is in the same little box as the exit so i am not sure if this thing could ever actually work. Both the intake and exhaust are in the same place even if it actually produced any ozone, it would take the lease path of resistance go out the intake. I would not suggest purchasing the HCD-55 based on my experience.

Much better price than the OEM replacement ozone generators sold by the various spa parts companies. I'm not entirely convinced that an ozone generator makes much of a difference, especially in a spa like ours that doesn't have a 24/7 circulation pump. However, for the price it really is a no-brainer. This was a 15-minute installation in our Healthy Living HL-7 hot tub.

Seems to work fine. Easy install. I think it only runs when heater is on? But havent had a ozone smell really in the water. But does seem to prevent my cover from smelling.

I have a Marquis spa that is about 20 years old, and this ozone generator replaced the original UV light generator. It was easy to secure this item in the hot tub, and the tubing just plugged in to the existing tubing with minimal difficulty. The plug on the generator plugged right in to the my circuit board in the same place as the old generator, so wiring was a snap. Very happy with this product.

The one in my spa runs 24/7 and I usually get about a 18 month ozonator lifespan. This model is my favorite as it works good, lasts the expected amount of time and is reasonable in cost.

Easy installation for replacement ionizer. Quick delivery at fair price.
