How do I slow it down??


I love my Fluval 406. I really, really do! My water looks amazing atm, but I want to slow the flow. I've already turned the outflow to face the corner of the tank. Any other suggestions? Is there anything I can buy to put over the outflow that won't damage the filter? What do you guys suggest?

How about build a DIY PVC spraybar that goes across the back of the tank pointed forward. This would diffuse the output over a larger area and would provide adequate flow through the entire tank.

Hmmm.... I can't put a spray bar over the top because the lid sits flush to the top of the tank but I like the idea. Might be able to adapt that somehow...

One of those fluval edge foam filter intake things always slow mine down.

That's what I did. Fluval edge pre filter looks like a black microphone pop filter, pop it on the intake tube and it slows the intake, thus also slowing the outflow. Also prevents flora and fauna from getting into your filter!

Cool! Thanks, guys! Will have a look at one of those.

Doesn't the Fluval 406 have variable output? Can you just adjust the flow using the little lever? Or is that bad for the impeller?

Your supposed to use the white lever. I have a 106 on. 9 gallon tank and its slowed to about 70%. I crank it up when cleaning but the fish seem to like it a little slower.

I've done that, thanks but it still seems quite fast. I don't think it's bad, you just need to be careful you don't do it too much or it will leak apparently.

add a bunch of inline components! (UV light, heater, co2 diffuser). that'll add resistance and slow things down!

If adjusting the flow isn't enough I'd make a homemade spraybar. Just get some pvc with 90 elbow and drill the holes. If it is still to much either use a longer piece or drill larger holes. For the color you can always rattle can it black (or whatever color you want). I did this a while back to decrease circulation but keep the same flow (GPH), and cost me about an hour of my time all together and less than $10.

I would not add anything to slow the flow by obstructing it, as this simply puts extra strain on the motor. If things are that bad you would be better off buying a filter with a lower GPH rating.

What size is your tank?

Yeh - sounds like the filter is too much for you. Perhaps downgrade to a 305? Depending on your tank size, of course. As others suggested, spray bars are good for easing the flow as well.
