I much prefer Eheim to Fluval. It's like comparing Ford to Mercedes. In the end the Eheim is such a better product that it will far exceed the life of a fluval. They run silent and are easy to service. The tubing that comes with them is far superior to that vacum cleaner hose that comes with the fluval.
In marine applications it is only recommend to run a canister filter on fish only tanks.
