Kold-sterile vs. RO/DI

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.

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.

What does HiS stand for?

All successes in conservation are temporary. All defeats are permanent.

The product literature seems slanted to me. I would not
use it.

If you want a filter unit that does not waist water, then
go with a quality DI unit instead.

Obviously the kold-sterile is some form of DI, but it does
not look too great to me.

Is the DI where most or all of the waste is separated?

With DI you have one medium that removes positive charged
ions, and another medium that removes negative charged
ions. The medium is in the form of beads.

My question was moreso about the waste. Is there water waste coming out of
the RO part or is it all made/separated in the DI. Any suggestion on that
DI that you said would not waste water?

Keep in mind that with a DI, the medium is more expensive
than the medium in RO, so while a DI does not waist water,
it does cost more for the medium, and water is not that
expensive. DI uses ion exchange.

Kent Marine sells a unit, and there are many other
manufactures.

The way that the RO works is that water is passed through
a RO membrane, while some water is allowed to exit without
passing through the membrane. This water that does not
pass through the membrane is your brine water.
