Using multiple canister filters?

April 30, 2008 9:34 AM

Is it possible to connect two external aquarium canister filters in the same closed loop?

I have two eheim filters, with one being about 2x the lph of the other. If I put the more powerful filter after the less powerful one would this set up work?

I would probably use thing in parallel, not serial, configuration. It'll take a bit more tubing and a couple of Y connectors, but either way you arrange it serially you'll likely shorten the lifetime of the motor on one or the other.

Put them side by side, run a Y connector at both edges, and let them share pumping duties.
