Bioflow Aerobic Filter

I have just started using the bio wheel shown in the photo. I have had it some time and tried it on my starter tank about 4 years ago but found it took up too much room. Now that I have my 120 ltr tank up and running I thought I would give it a try.

I was wondering if anyone else is using one and what they think of it. My only comment is it is much quieter than having a spray bar trickling all the time.

Here is the description on how it works.
Hydor BioFlo is a rotating deflector which, thanks to the supplied adapters, can be connected to the water outlet of the pump or filter operating in your aquarium. The 360 rotation is guaranteed by the force of the water flow that passes through it, with no extra energy consumption.
This is how the Hydor BioFlo works:
The deflector rotates 360 pushed by the power of the flow rate which passes through a gearing. The water then creates a pleasant wave effect moving plants and/or anemones in a very natural way. This allows to increase considerably the oxygenation. The rotating water deflector becomes an innovative aerobic filter thanks to the sponge that captures the inactive bacteria from the water surface of your aquarium.

If you don't like the trickling sounds of the other outputs, just put them below the water level. The only potential issue is that the output flow on this might be of a higher velocity than the typical submerged bar. Otherwise, it just seems to take up a lot of space for what it might do... of course the picture may make it look larger than it really is.

Hi Jeff,

I did zoom in a bit, the sponge is about 5" diameter, but the deflector does give a gentle more natural movement of the plants and surface rather than the water racing across the surface in one direction.

The tank has been running for a week now, I changed about 20% of the water yesterday and checked the water condition today and so far no spikes. Zero Ammonia, Zero N02 and 1 mg/l N03, GH=3d,KH=6 and pH=7
