Fluval U4 internal filter

How well does the U4 work as an internal filter?

It would be an additional filter for me, sorta like a powerhead per say. Since I'll have a Fluval 406 it might not be enough flow around the whole tank.

It'll be in a 75 gallon planted tank. I don't have it set up yet but this would just be an additional filter. I'm ordering the newly released fluval 406 as my main filter.

Well, yeah but all the powerheads I've tried are extremely loud. I've tried the maxi-jet's, koralia and a petsmart brand and you can hear them really easy out of the tank, like a buzzing noise. Not the greatest thing when you trying to sleep.

I'll only get one of these if the 406 isn't as giving a flow though the whole tank.Which it most might not I'll get this or some koralia powerhead.

But with the powerhead I won't have any filtration it'll just be blowing things around...

Thanks for the video daffyfish. It looks like the only downfall to this as mentioned above is its bulkiness. I probably could hide it easily with such a large tank with some tall plants and I should be good.

Sorry, no I didn't actually buy it. Instead I'm using a Fluval 406 and a Koralia nano 240 gph. The look of the u4's look in-tank didn't fit for me in a planted tank.

The flow can be managed since it has an adjustable spray bar and plants getting blown around shouldn't worry you at all. Good luck!
