Sorry to say this, buy there are other choices. I use a trickle filter on my
plant tank. I've never used a cannister, so I don't have any effectiveness
criteria on it, but I find my trickle to be *very* easy to maintain, and I get
most of the hardware (CO2 reactor, heaters, etc. out of the tank and into the
sump. When I want to clean my system, I just replace the piece of bule-white
filter media that sits on top of my trickle tower.
I'm also slowly removing the media from my filter and letting the plants take
over with NHx removal. So far, so good, but I still have 1/2 gallon of
bio-balls in the tower.
BTW, I wouldn't come close to dishing out the money for a commercially built
trickle filter. They're just too easy to build, and you can conserve at least
half the cost if not more by building one yourself.
