SunPurity Mineral Purifier

Electro:
Hi Guys,

I'm a newbie to this board.  But, I have been reading the posts of the past 2 years for several days.

At my wife's request, we are buying a hot tub.  I had never considered such a thing.  But on reviewing the potential benefits, it seems that this may be a very good thing, especially for arthritis, sore muscles and circulation problems.

After mulling over the possibilities and visiting various dealers and wet testing some tubs, we settled on the Sundance Maxxus.  My wife wanted a big tub, with a large space to stand in, and I thought this tub would be interesting to exercise and play in.  Also, I have become convinced that the Sundance brand is at least fairly good, which is to say - better than most.  The tub has been ordered to get the colors my wife wanted, versus the one color pattern that both nearby dealers had in stock.  It should arrive in 2 to 3 weeks, according to the dealer.  I'll give more details if anyone is interested.

I have researched the matter of hot tub chemicals, which seems substantially different and somewhat more complicated than when we owned a 16 ft x 40 ft pool in Torrance, California.  I plan to go with the Nature2 mineral purifier (which actually provides silver and copper ions to the hot tub water, according to
Regina at the Sundance user phone number 909-606-7733).  I'll also plan to use the Sunzone CD ozone unit and 0.5 ppm chlorine from diChlor.  The advantages of using this system with silver and copper ions for disinfection is well documented in the scientific literature.

I was surprised to find that the Sundance SunPurity mineral spa purifier is identically the same as the Nature2 product, except that the manufacturer (Zodiac Pool Care, Inc.) makes the Sundance product to fit in the automatic brominator space of Sundance tubs.

I am disappointed that the retail price of the Sundance product has been substantially enhanced.  My Sundance dealer charges $33 for it, whereas the normal Nature2 version is apparently routinely sold for $18 to $23.  This is the sort of thing that makes me angry.

Other interesting stuff:  I'd like to tell you about my experiences with hot tub sales folks who were all honest and straightforward, but - alas - several were not.  I could tell you about how I'm strengthening the structure above my garage ceiling, above which is a deck where my wife wants the hot tub.  My architect has provided plans to assure that an additional 8,000 pounds can be supported.  The hot tub weighs exactly 1,000 pounds dry weight, 5800 pounds filled with water, and 7200 pounds with the 8 (175 lb) folks who can sit in the tub.  Also, my approach of installing the 60 ampere GFCI circuit breaker includes a new 100 ampere feeder circuit, for later application to my Krell stereo sound system.

Does anyone know of Sundance dealers who sell the SunPurity product for a better price or whether it is available from other than Sundance dealers?

I tried the SunPurity Mineral Purifier in my Cameo.  I really did not see where it did anything.  I not sure if there is enough water flow through the compart space for it.  I have thought about trying the N2 that fits in the filter and see how it works.

electro,

congrats on your new buy...i looked at the maxxus but never imagined needing on that large...and to exercise in a hot tub?? whew, talk about breaking a sweat!

seriously, i am using the monarch silver cartridge that my caldera dealer sells for $40 a pop.  so i have definitely been interested in other choices.  my sundance dealer never mentioned a silver compatment when shopping there.  i have not had my first water change yet, but the next one i do, i am going to run without the silver and see if it makes a difference.

oh, and i also got excited about your pending krell purchase.  i have always been in awe of the master reference subwoofer...may need that architect again if your going to place that anywhere but the ground floor!!

Brian,

Thanks for the feedback.  :)  How or with what other products did you use the N2?  Did you use MPS, bromine or diChlor, etc?

The Sundance factory rep told me that the regular Nature2 product would not work in a Sundance tub, because there is no way to achieve correct water flow in the Sundance filter system past the Nature2 minerals contained in the regular device.   They apparently got the best water flow that they could to the N2 material in their SunPurity design. :(

I wonder what results others have gotten with Nature2 or with an ionizer or with Rain Forest Blue, which apparently contains copper only.

tubin,

Thanks for your insightful reply.   ;D   Of course, I'll dial down the temp for exercise in the hot tub.  The instructions say to never exercise with the temp over 90 degrees.  Actually, I was thinking of letting the temp drop to about 75 degrees, more like a summer pool for exercise.  I remember my younger days when pool temperatures of 67 to 72 degrees felt quite good when exercising or swimming.

My wife will want the tub at the normal "hot" temperature.  With the ambient outside at 70 now, how long does it take to cool to 75 from 100 degrees and how long to heat back up?  Anyone know?

Krell is the best.   8)   I power up my B&W 800 speakers and the sound clarity is truly excellent.  I can't wait until Krell releases their upcoming SACD player.  As their SACD Standard player is better than most anything available, the new player should really set the state of the art.

Have you or others ever measured the level of (silver and copper) ions in the water?  If so, what levels did you observe?
