I had this idea for a filter for a fish tank, I dont know if it has ever
been done before, but here was what i was thinking.

Basicly it combines an undergravel filter and a regular powered filter.
But my idea was to build a regular powered filter into two sections one
that went directly into the undergravel filter (my therory is this would
increase the effectiveness of the undergravel filter while keeping it
cleaner than usual), and the second part could be set in the normal area
for a regular filter to collect floating material.

I also thought about a top filter to clean material that floated at the
top of the water.

It could possibly be expensive to build but i think it could work



what does everyone think?

It has been talked about before here with netmax. It does increase the
effectiveness of the undergravel filter but it reduces the biological
apect of the UGF. I currently have an old hang on back that I can hook
to the uplift tubes of the UGF. I don't run it constantly, maybe once
every couple of months to get rid of a lot of the crap that has built up
under there.

Since gravity and the suction is pulling all of the stuff down, you
don't need to top filter. (Very infrequently is there stuff that floats
on the top).
