Introduction: Cheap and Easy Aquarium Filter

Buying fish filters becomes a bit pricey over time so why not make your own

Step 1: What You'll Need

ok we'll need a used aqua-tech: ez-change filter
a pair of scissors
hot glue and hot glue gun
activated carbon you can get it at walmart or any pet store
web vent filters you can get at most hardware stores

Step 2: Now We Wash

wash the filter
and over a trash can pull the blue part of the filter off and emtey the activated carbon
pick off as much as you can so it looks like the fourth pic

Step 3: Triming the New Filter

now take one of the vent filters and trim it so it fits where the old blue filter was

Step 4: Now We Glue

glue one side at a time then press to make sure it sticks well
leaving the long side unglued

Step 5: We Fill

ok now we fill squeese the filter to make a little opening and pore the activated carbon in

Step 6: About Done

now glue the last side  and give it a little shake to even it out
and trim the top and bottem

Step 7: Done

just put it in.   this is my first instructable constructive criticism welcome

Thanx but this is a filter pad/ filter medium, not a filter. I WILL use this idea eventually but I am looking to make the filter to use the medium with. I only tell you this because it keeps popping up on my search for the FILTER

I have been doing this kind of filter reworking for quite a while and it is truly a good idea. Remember that what you really need is to make enough room for bio filtration not too much carbon inside! One sign that you are overfeeding is a filter that gets clogged very quickly. Good Instructable well done and useful too.

Is there a specific hot glue stick needed (or more specifically to be avoided)? Is it safe for the fish?

I just tore off my old one and stuffed floss behind it. Its more of a medium for bacteria/whatever to grow on than an actual filter.
