Thats what i was thinking , I will see how long this one goes on a fill up and try to find a larger canister. Might be a suprise on how long it goes on a 122 cu ft bottle.

I was thinking of adding one to my tank as well. I ordered color change desiccant from McMaster. It was granular instead of beads.... but should work fine. I think a filter like yours will work better than just suing a large tube like Jody did....
