I am writing to tell you how much I appreciate the Clear Choice treatment system you developed for hot tubs.
I am an engineer, I like to measure stuff, so I have long records of maintaining various hot tubs I have had and used since the early 1970’s. This long term usage involves a number of different systems, chlorine, bromine, silver ions, diatomacious earth, etc. If the pH was OK, the Total Dissolved Solids was off. If those were OK the Total Alkalinity was off. If those were OK the water was cloudy, etc, etc. I’m sure you know the drill. What a pain that has been.
I installed the Clear Choice system according to instructions provided along with a new filter March 3, 2004, and the results have been somewhat unbelievable to me. I have done nothing but add 3.75 ml of the Water Treatment Material each week, and the water is crystal clear, pH about 7.8 (I may have to add a touch of “Spa Down”), and Total Dissolved Solids is 330 ppm, the same as when I first filed the hot tub almost 2 months ago.
I’m using a “Marin” model hot tub by Sundance, holding 320 gallons with a 125 sq.ft. filter running at 104-5 degrees F with electric heat and an insulated cover. It is located outside (just a windbreak on 2 sides) south of Santa Fe, New Mexico, elevation 6,300 ft. above sea level.
I originally installed this hot tub November, 1998, and two of us have used it regularly for 10 to 20 minutes each evening since then. It has never been this clear and this balanced for such a long time period with so little attention.
Again, thank you for Clear Choice, I’m looking forward to continuous long time enjoyment of near maintenance-free usage of my hot tub with Clear Choice water treatment.
