Okay, Ed, I recognize that Marine Monsters has a commercial investment in 
this product, and I'm sure it works every bit as well as a Brita at removing 
all that stuff.  However, the list of things your wondermachine "sorbs and 
restricts" does not include calcium or magnesium.  Therefore it is not a 
water softener, since these two +2 valence ions are what constitutes General 
Hardness.  Also, you don't list carbonates, which is what Carbonate Hardness 
(go figure) is all about.  And while it is true that RO wastes a lot of 
water(unless of course you redirect it to your lawn, your toilet, or 
whatever) DI doesn't waste any at all.  Yes, I reconstitute to the level of 
1บ GH and KH, then add Natural Gold for the plants, which brings conductivity 
up as far as I want it.  In my community tanks, however, I use it straight 
from the tap, and let the plants and some peat reduce the hardness to about 
3-4บ.
