I use a Magnum 350 with micron filter on my 55 gallon tank, which is
otherwise unfiltered. The tank gets a weekly pruning and 15% water
change. After that, I run the Magnum for 1-2 hours to clear the water,
then I put it away.
There were several reasons why I took the filters off this tank. One
reason was that I got tired of cleaning and otherwise messing with filter
media. I only later saw any use for the weekly polishing, and I might get
by very well without using it as frequently as I do.
Setting up and taking down the Magnum and bleaching the micron filter is
very easy, but it's *way* more messing around than I did when the tank was
still constantly filtered; ease of maintenance isn't much of an argument
for unfiltered tanks when I do it this way.
If I wanted to use the Magnum for constant filtration I would use the
media canister and a sleeve to fit over that for biological filtration.
The micron filter tends to get plugged in regular use, and I don't think
that Marineland advises us to use it that way.
