Make Your Own Fishtank Filter Cartridge

August 24, 2010

I am a huge Fish Geek.  Please don’t tell anyone. I wouldn’t want my reputation as a “cool kid” to be ruined 😀  This great idea came to me via Quiltie a couple of years ago to help diffuse the cost of my hobby. I just got around to taking pictures of the process 🙂

Make Your Own Fishtank Filter Cartridge:

All you need to do this is the Old BioBag Cartridge you are replacing, Loose Fishtank Carbon ,Polyester Quilting Batting, Needle and Thread.

Your Cartridge will look like this to begin with (probably alot dirtier though):

Notice that at the top middle of the bag, located on the long plastic piece is a clip. Remove that clip, along with the plastic piece and peel off the mesh filter which will be full of carbon. Dispose of the filter and carbon.

You will be left with a frame that looks like this:

Cut a rectangle out of the Batting large enough so that you can fold it over the frame so that there is an inch or two extra material on all three open sides.

It will look like this (I cut mine uneven but when it’s finished it will not matter because the extra will be trimmed away. Sorry about the yucky table top I put it on for the picture. Painting that piece is next on my to do list):

Fold the material over the frame and hand stitch at the side and bottom. No need to stitch at the top, the plastic piece and clip you removed earlier will hold it. Cut extra Batting off, leaving about 1/2 an inch past your stitches. You will be left with a sleeve around the frame not unlike the one you disposed of earlier.

Depending on the size of your Cartridge pour in the Fishtank Carbon (I used about 3 TBSP for a small Cartridge). The kind I use looks like this:

Fold the top of the Batting over the top of the frame and replace the plastic piece and clip. Trim the extra batting from the top

It should look like this:

Rinse your Cartridge ,as you would any new one, to remove the dust from the carbon and put in your filter.

I bought my box of carbon about 5 years ago and my batting was free because I’m lucky enough to live beside a Quilter who often has scraps. So it costs me about .20 per filter change to our Filter every couple of months.
