Ok, I sure don't have all the tech stuff about filtration down pat.
I
have a very general understanding.

Here's my question -- Why not rinse out old filter cartridges in
running tap water & reuse them?



Naturally, the manufacturers would prefer you buy new carts. g I
have 2 emperor 280's and have never bought replacement cartridges for
them. As long as the bacterial colony is large enough in other places
(i.e. bio-wheel) to support the fishload, rinsing that media off in
the sink won't cause any trouble. In a heavily stocked tank, it would
make me rather nervous, as the bacteria in the cartridge are probably
needed.
FWIW, I am also a firm believer that the big push to use carbon
is largely driven by the people who make the carbon! I use it on an
'as needed' basis only.
