We talked a bit about ozone in the question about the cost of running a hot tub. Now that you understand better why a water management system is so critical to your hot tub experience, let’s talk in more detail about ozone.
Ozone is an O3 molecule. It is typically created by passing oxygen over an ultraviolet bulb or a corona discharge chip. This creates the unstable ozone molecule, which will eventually stabilize to not only kill, but burn up organic material (bacteria, dead skin, or other great stuff that can be introduced into your hot tub!). By adding an ozone system to your hot tub, you can use the ozone to do some of the purification process for you, reducing the need for chemicals.
What are the differences between ozone systems? There is a critical difference that determines how effective your ozone is at attacking organic material. Most ozone systems are added into the spa and inject the ozone stream directly into the hot tub body of water. The ozone then quickly rises to the surface, not coming in contact with very much water, and therefore not doing very much purifying in your spa. Not only that, but the longevity of ozone is much longer in air than in water. So you now have a layer of ozone in between the water surface and the bottom of your cover (you can smell this ozone build-up when you lift the cover). This ozone eats holes in your pillows and covers over time, and allows water to get into the foam of your cover, causing it to become waterlogged.
An ozone system that is incorporated into a water management system will introduce the ozone into the plumbing of the spa, it will then take the ozone and water and vigorously mix the water and ozone in a mixing chamber; leading to a much higher level of purification because every molecule of ozone touches more molecules of water. Then, this mixture of ozone and water will be run though several feet of plumbing that is designed to allow the ozone to change back into oxygen before it enters the hot tub body of water.
Understand this – Humans are organic material, just like bacteria. Breathing ozone will start to irritate your throat. The first ozone system we described turns off the second you touch the spa control. This is because this system is not allowed to run while you are in the spa (so that you don’t breathe the ozone). But you have to ask yourself – when do you want your water to be clean? – When you are in the hot tub! The second system is safe for use when you are in the hot tub, and runs 24/7, keeping your water crystal clear and clean and creating a safe environment for your family.
