I have an Eheim Ecco on my 35g, works great.
Probably the easiest would be a sump-like setup: have one tank
higher than the other, have the output of the canister go to the
upper tank, input in the lower, and an overflow box on the upper
tank feeding to the lower tank.
But store-bought overflows ain't cheap. Either make one yourself
(a bunch of DIY plans out there - just do a google search), or just
run a siphon from the upper to the lower tank at the same rate as
the canister rate. Tubing and a gate valve or ball valve. Although
this is potentially more dangerous because water will continue
flowing when power goes out. Hmm, maybe you should stick with an
overflow after all. ;)
That being said, I think I would just bite the bullet and buy a
larger tank now. That way you haven't wasted any time cobbling up
a short-term solution.
