This is an easy to build enclosure for the home made biological pond filter. My enclosure has been built to the dimensions of the tote I used so it may have to be scaled up or down depending on your filter. The sides are glued and screwed together. I used Titebond II and outdoor deck screws. Other than that I pretty much used scraps and recycled 2×4 material.
There is a sketchup model here if you would like more detail.
