for some reason I thought there was a test or something. So it sound to me like if the tub is 4 years old time to replace it.
So what is the best ozonator? Which one lasts 10 years and requires no attention?Ozonators come in many different varieties and qualities. Some will last 5-10 years, others much less. Some CD ozonators need a chip replaced yearly, others never in the life of the unit. There are UV ozonators that need a bulb replaced periodically and there are solid state UV ozonators that are a higher quality.
It is difficult and expensive to test for ozone and maybe practically impossible in a spa because of the very small amount introduced to the water in relation to the volume of water.
The yellow substance is nitric acid produced from your ozonator.

What brand of spa do you have and what type of ozone were you using?
There is a spa ozone detector sold. Just do a Google search for "spa ozone detector". It's got a picture of a dog on the packaging. Never used it so I can't attest to its efficacy.
Well i can tell you that when you bought your Cayman you had 2 options for an ozone system. One was a UV and the other (which also cost more) was a CD ozone. That could explain some of your issues given that it used a fairly "cheap" ozone for their UV models. BTW is your spa running on the 24hr Grunfros circulation system with the Laing Heater or are you using the 2 speed 4hp with Stainless steel heater?
I ask because you tend to have better results with the 24hrcirc pump rather than their 2 spd system. You really shouldn't get cloudy water after 3 days in any spa provided that your chems are in balance and you didnt bring your dog in the spa![]()
