Hi Ludger,

Yes and no. Not much of an answer really. If your bio filter is oversized, the downside is you will only grow bacteria to the levels that you need (relative to your reduced nitrogen input for substrate). Also with larger than needed biofilters the volume is larger proportionate to the volume of the media and retention times in the bio can be too long. There is no real downside aside from cost and space.

Paul

If you are refering to aquariums, you may still need some dacron or fine solids filtering.

Hi Bubbles, Fludize means the media in moving in the water. Bio balls are heavy so do not move well and are often used as a submerged static filter or media for a trickle type of filter. We sell K1 media which works very well in a moving bed type of filter and it is often the choice of most aquaculture operations. Regards Paul
