I got tired of paying a whole-lotta-cash for my Cascade 80 fish filters that I was having to replace every couple of weeks. So I decided to make my own, using furnace vent covers, activated charcoal and and an old filter. I would imagine that this would work for any filter that is a charcoal/batting material. It's been a couple of months and my fish isn't dead yet, but don't hate me if yours dies.TrainWithThom.com
Step 1: Step One!
Alright, so you'll need 3 things:
- Activated Charcoal
- Old Cascade 80 fish filter - I would imagine that this would work with any other type of cartridge filter
- Vent filters - these are used to cover your furnace vents it your house. I would image that a sewing store would have some similar type of material
Step 2: Step Two!
The second step is to remove the old filter and charcoal from the filter cartridge. I used a screw driver and peeled it all back; you could use any method you want. Just get it off and pour it out.
Step 3: Step Three!
Alright so you have the old filter material off, now it's time to pour some new charcoal into the old cartridge. I put about two tablespoons in, as that's about how much is in the old filter. It's important to have this stuff as it is what balances the water.
Step 4: Step Four
Now it's time for you to cut some of the vent filter, I found that it works best if you use 3/4ths of the vent filter folder over on its self twice. You can use the other 1/4th after a couple of replacements.
Step 5: Step Five!
Now it's time to slide it carefully back into the filter holder/pump assembly.
Then throw it back on you tank, prime, and plug it in!
Step 6: Step Six!
Great, now your fish can enjoy a clean tank and you can enjoy some extra cash in your pocket.
