the big thing is you want to get all the chemicals out of the water. Most
RO systems are about 97% efficient, HiS systems are usually around 99%
evffecient, and RO combined with DI is usually around 99.6% effecient. Now
some of the other systems are great for large particals as well as bacterea
and other critters but when it comes down to gettin the minerals out they do
not compare.

I know the reef community preaches RO/DI. I'm wondering if anyone on this
forum has had any personal experience with the Kold-sterile filtration
system. I just don't like having my water being wasted making RO/DI.

I only find some old articles/forums about this product. Sounds like they
were *almost* popular about 5 - 6 years ago.
