  1. Burlington review by Ian Baines on 6/22/2015

    Received within a few days of order - the product is well made and very easy to install. I did not pay attention to the water balancing that is supposedly required - merely adding 10 cups of salt to a new water fill. I have left the hot tub pretty well unattended now for a month. The water remains crystal clear and there is no evidence of algae, cloudiness, etc. It works just as well as my salt water pool. I highly recommend this product and this company.

  2. ChlorMaker system did it for me review by Michel on 5/9/2015

    I suffer from eczema and the bromine in our tub was causing a lot of difficulties for me as my skin kept breaking out all over with red itchy blotches. Just not enjoyable when you own a hot tub. So the salt water conversion kit - ChlorMaker system did it for me. So I can now enjoy my hot tub experience and don't worry about my eczema coming back. Gord and staff were very thorough throughout the ordering process, calling me back to explain how to set up the saltwater system. I will be recommending this to anyone I know who also has a hot tub. Thanks Gord and staff for all your help.

  3. ***** 5 Stars ***** review by Francis on 5/9/2015

    The Chlormaker DO works great! No more chemicals, NO MORE SMELLY WATER. We can finally enjoy the wonderful fragrances of the flowers and plants around our spa! Installation was a cinch. I didn't have a 110 volt outlet close by so I found an open 110 volt post on the main board of my spa that I could plug into. The wires included with the kit make for a clean installation. Cranked it up to 8 for a couple days to build up initial chlorine levels. Now I keep it between 1 and 3 depending on our use of the spa. I'm amazed and thrilled! The explanations over the phone were spot on.
