I got a Magnun 350 with the bio-wheel pro 60, and is a lot bigger than the
Emperor 400 on a 33 G and I'm using a spray bar from a fluval 404 (because
is easy to clean) and a PowerHead 402 and I have alot of turbulance under
water and the bio-wheel wasn't doing a good job because my pH was 7.2 - 7.6
but after a month or two is no doing noise at all and my pH is 6.6 - 6.8 all
the time, my plants are doing just fine and if you have plants you need some
movement in the water as it is in nature, if you have no movement all waste
and extra food will burn your plants...


I hope you understand my english, because is my second language and I'm not
very fluent.... and remember aquariums are try and error !!!

Hi All,
Just set up a new 55 gallon and planning to make it a light- to
moderately-planted tank, without CO2. I currently have an Emperor 400
on it
that is making more noise than it should, and I am going to return it,

BioWheel filters take a good 3-4 weeks to break in.
You might be experiencing a waterfall/splatter effect now to go with
your strong current.

To reduce that effect, fill the tank as high as possible. The
additional water will prevent the water from falling as far, thus
reducing the turbulence and the splatter noise.

You can also try reducing the amount of water intake. I wrapped a
piece of velcro around the intake tube which raised the tube a quarter
inch or so.

Once broken in, the biowheel will become water logged, spin much
slower, cause less turbulence, and drip very little to make splatter.
At that time you can remove the velcro if the current is too slow.
