I'm looking for a small micro mesh (or something with VERY small holes) resealable bag for my carbon and GFO. I have a 20 gallon AIO and I use the BRS media bag which works great but their smallest size is 8"x4" which is comically large when I put my 1-2 Tablespoons of GFO/carbon into... does anyone know of any smaller resealable media bags that I could use? I found some online but its hard to gauge how large/small the holes in the bag are (I don't want all my media leaking out). TIA!
