Ok so this is what I've managed to find.
First picture is what I think may work for my bio. Second two are my choices for the carbon. Since I'm trying to set this tank up mostly for discus I'm thinking of putting in two bios? Let me know what you think?
Also I found the boxes for the canisters that's the lid of them in the last pic. In case you want to look for them
My only request..if you end up at a plumbing place let them know it was the "missus" who came up with the idea to use them on her tank.
