Reverse Osmosis filters?

[Dan J. S.]

Are there any non-industry RO filters for aquariums? A filter like this
would totally eliminate the need for changing water, or am I mistaken?

You mean filtering the water thru RO instead of say thru a Canister filter?
If that's what you're implying, then you are correct, you wouldn't need to
change the water, but that's because you wouldn't have any fish. :) They
can't live in RO water, they need certain minerals, etc. to be present to
allow their bodies to function, RO filters would remove these.

:o), but what if you continuously added minerals using a coral substrate?
;~)

RO filters produce a small amount of RO water relative to the amount of
waste water produced, so your RO aquarium filter would empty your tank,
and then your fish would die ;~) You could replenish the water lost to
the RO process, but the act of replacing the water would effectively
become an automated water change system, making your RO superfluous.

It was a darn good question though.
