I am about to become a 1st time hot tub buyer (hopefully). I have visited several local dealers and am now trying to sort out fact vs fiction and was looking for some help. I have not wet tested tubs yet, and maybe that will make one tub stand out from all of the others, but right now I am trying to do a little comparison. One of the items that is high on my priority list is high water quality with low maintenance (if that is possible). I am by no means a chemist, nor do I want to become one. My sense is that these systems are fairly similar but marketed very differently. Any insights would be greatly appreciated.
One other question, can the Onzen actually go a full year without water changes? That does seem to be a big differentiator.
Thanks.
