I'm going to build a plywood aquarium (8'x4'x4') and want to know what kind of filtration is going to be the best? i have access to plastic 55gal drums, are there any designs here at MFK to set up a new filter using these drums?
and here is how i made my own filters for the 15' pool that housed the large cats
first i bought 3000 bio balls , then 2 large garbage cans and 2 red tubs from lowes
second i drilled the drain holes in the garbage cans and filled them with bio balls 3/4 way full

then i cut the bottom 3 inches off of the red tub and then drilled a million holesx2, then i
cut a piece of filter material to fit in the new drip tray, i set it on top of the bio balls and cut a hole in the lid to fit a 1" inside diameter hose that i ran to a tetra 1000 gph pump, and were done, very easy and now we can filter 2000 gph with these filters, set up a couple of 2x6 across your pool and set them up there,
