easy DIY CO2?

I will just try taking the foam filter out.
I wanted a much smaller because design that would not be very noticeable in the tank, the Elite looks like a tiny submersed filter which it pretty much is.

I didn't put it on the outside of the filter because that would look very un-natural and tacky..:silly:
 
Jag1980's pic pretty well sums it up, though I'd either strap the bottles to something or set the trap on the ground next to the bigger bottler before taping together - and I'd use at least 2 of the big ones.
