Over the last several years I have had ca number of Eheim canister filters. And they have all leaked at some point. I am tired of mopping up water and I was hoping there is an alternative to the canister filter that would do well on a well stocked 100 gallon cichlid tank. When they work the tank looks beautiful. But I never know when they will start leaking and once they do it is very difficult to diagnose the problem. Any suggestions?
