It can reduce your chemical levels required to achieve proper sanitation.I don't think I'm highjacking here but concerning the Nature2, does that make the reading of strips different, or do you just have to guess at how much to cut back on chems? I'm interested in trying the Nature2, but I don't know how to tell how much it actually helps in the chemical part.The claim is you can run as low as .5 ppm of free chlorine with an N2 cartridge in place (following all guides for use).

The Sundance dealer, whose tubs use UV, told me that CD degrades plastic and rubber components faster. Is this a big enough drawback? Why did Sundance switch to UV? I assume they were using CD before...Off-topic, but there have been studies showing that ozone reaction byproducts are harmful to health. Have any studies been done on the health effects of hot tub ozone?
And if we could get back on topic and tell me which of these models/manufacturers you'd choose on the basis of reliability, maintainability and efficiency.Thanks
I can't speak of any specific studies but I know I did sell a tub about 6 months ago and the lady wanted us to disconnect the factory installed ozone before we delivered it. I didn't really get into specifics but she claimed respiratory issues with breathing in ozone could lead to some serious problems for her. This is the first time I've heard anything about it, so I'd have to do a little more research
My personal opinion is that Bullfrog spas has the most revolutionary design in the entire industry. From top to bottom, they have created an extremely well made spa that offers unparalleled hydrotherapy. Fyi, the jetpaks do not take away from inside space. As a matter of fact, they create more space. If you compare tubs of the same overall size, the Bullfrog will most likely contain more gallons. For example;The hot spring pulse is 7'5" x 7'5" x 38". The Bullfrog A7 is 7'4" x 7'4" x 36" which is a little bit smaller. The hot spring has 380 gallons and the smaller Bullfrog has 430 gallons. This is yet another advantage to the JetPak design. The manifold on the back of the JetPaks is lower profile than traditional plumbing and fittings.http://www.hotspring.com/shop-hot-tub-models/limelight/pulsehttp://www.bullfrogspas.com/listings/display/140/40/a7As to wood frames, there was just a thread the other day where a guy was asking about replacing a rotted wood frame component. Wood rots, plain and simple. Metal rusts. Plastic will not rust, rot or corrode. ABS bottom is also a good thing. It keeps moisture, rodents, and insects out of the hot tub. Also, without this, a wood framed hot tub will have wood directly touching the ground. I have replaced hundreds of older wood tubs with no abs base and many of them had evidence of rodents and rotting wood. Sometimes they just fall apart when you try to pick them up. Hot Spring at least uses treated wood for their base, and hard foam to seal the bottom. Last I saw one though, the rest of the wood was not treated.I'm not saying that the other tubs listed are not good. In fact, as mentioned earlier, they have excellent reputations for a reason. Having seen Bullfrog Spas dismissed here by some of the other guys, I just want to make sure that they are accurately represented. In the last 7-8 years, Bullfrog has really stepped up their game. They are an amazing hot tub and my favorite hands down. For the record, I have worked with most of the other listed tubs over the last 17 years.As to circ pumps, there is one factor that is never discussed. As far as I know, Circ pumps are generally in a closed loop, meaning that they do not tie into the rest of the jet plumbing. This means that when the circ pump is running, the water in the jet lines is not being circulated. That water only gets moved when jet pump kicks on. This may have been addressed by some manufacturers, but as far as I know, this is how most systems with a circ pump work. Please correct me if I am wrong. I'm not saying this is a reason to avoid circ pumps, it is just another factor that I don't see accounted for in discussions.
