Where do you get the .....

  • We are currently upgrading MFK. thanks! -neo
I've noticed that petsmart usually doesn't have it, but local LFSs usualy do, either in packages or on a cut-your-self/ per foot roll. If not, you can order it all over the internet, but ebay is probably the esiest.
 
Yep, I just get the big sheets from the LFS to cut to size for my Fluval canister
