Good explanation. Since SMARTMIST used to call themselves commercial cool-n-save it is my opinion that they cut off GDGI upon those enormous misting deals. Why wouldn't they use the cool-n-save for those. My theory is that they purposely tried to keep GDGI out of the revenues.
the stuff you spray on the fins to prevent scaling is extra and is patented by someone else
there is a chemical in the stock filter system that attaches to minerals and makes them irregularly shaped. if i recall correctly they have a patent on that chemical. it almost certainly has other applications that they have not even examined. there are also other patented chemicals that do similar things and do not belong to GDGI if i recall correctly.
