Will the filter last through one vacuuming? How do you clean the
filter? I'm not familiar with the Marineland vac product you speak of,
but I will Google it in a few.

I've tried various fiberous materials, gravel and block sponges. The
block sponges worked best aside from the house filter but the fine
particle filtration was really bad. Worse than the house filter by far.
However, on my two ten gallon tanks I use a block sponge on a small
powerhead and it works wonderfully. Maybe I am trying to move water
through the sponge too fast with the big pump (300gph). Maybe this is a
job for several filters of incremental mesh size. I dunno. I was really
hoping someone would have a simple solution, like pantyhose or
something...... Oh, and no pantyhose doesn't work either.

Thanks for all the help
