How do the fluvals work

[Joeyt66]

Just wondering how the fluval 404 system works? My brother is setting up an aquarium and neither of us know much about them. Are they an under gravel system or how do they work ? Im use to the aqua clears and have no idea how the canisters work . Just doin a bit of research for him

Well. They have two pipes. 1 for sucking in the water. and the second for pumping it back into the tank.
You have the one that sucks the water at the middle of your tank and the second one has a spray bar on it. So the water filtered is spread out.

I hope this is the answer you were looking for.
