I'd suggest instead that you use a submersible pump in your sump to
return water to your tank. Then run your Eheims off the sump so that
they pull water from the sump and return water to the sump. With this
approach you can size the submersible return pump to get the constant
circulation rate you want. You can also service your canister filters
without turning off the return pump. ~Tim
