This company, has at list 3 different websites with different names etc.. I purchased Eco3Spa from them, which is actually their own brand. The products did not work. The water went green within 2 days and cloudy. I had carried out step 1 as instructed, but was told that I needed to rinse out all of the pipes before filling using. This is not in the instructions. I emptied, the hot tub and tried again. Despite numerous calls to customer service, the problems persisted and the only answer I received was 'we are using the hot tub too much'. I have since changed to a different Active Oxygen system, which is working well. I did post a 1 star review on their site, but it seems that they only post the 4&5 star reviews. Definitely not a trust worthy company.
