Replaced an older 405 that had a leaky seal and a bad pump. My 406 is about two years old now and the Seal leaks and the pump died.

Rated 5 out of 5 by 1Bluefish Fluval filters
I've raised Discus, Africans, Angels and have found the only way to go is with Fluval filtration systems. The canisters are in my opinion the easy to clean and keep the water crystal clear. They trap a significant quantity of impurities keeping the tank clear and if you need to change the water to an Amazon or African quality there is a sleeve to place a water enhancer/modifier. The bottom line it does the job like mother nature would do keeping things clear and clean.
