The Black Knight vortex brush with anchoring wire at each end

Brush measures 102" long with a diameter of 4".

Ideal for catching extra particles from finding their way in to the biological filter,attatch to the inside of the vortex or settlement filter.

Simply insert a vortex brush in the path of the flowing water and you will be amazed at how much waste is collected in a short time. If your second and subsequent chambers are already full of media then you can use either one vortex brush strategically placed around the transfer port or you can use several to build up a barrier of them above the inlet of the vortex and below the outlet (assuming that your vortex is designed in this way). This will allow the heavy waste to drop to the bottom of the chamber and then all the waste that does not settle is forced to pass through the brushes thus allowing it to be caught.

You can coil one or two vortex brushes around the outlet so that the water has to pass through the brushes.

You can create a complete barrier filling the whole cross section of the chamber. The more brushes you use, the greater the amount of waste that can be collected and also the larger the surface area for biological filtration

Vortex brushes can be used in as many chambers as you wish. It is a good idea to leave some room in the first chamber to allow for settlement but subsequent chambers can be filled with vortex or filter brushes as shown.
