Thanks for the input.

I am still debating the project after doing more research. I mean, i can get the canisters for free and the incentive for using the filters i mentioned is i can get damaged ones free but the pump that would be required would completely defeat the purpose of a low cost system since it would require a rather large filter to keep the pressure high enough to get adequate flow rate

I do agree with the suggestions about media, i would need to figure out some sort of riser to get water to the bottom so it would pass through the media...

If i make any progress and am successful i will definitely report back, thanks again for the suggestions!
