Black Knight Vortex Brushes - High Quality Vortex Media

Vortex chambers are useful for filtering out heavy waste but less efficient with the lightweight particles. So even if you get a lot of waste in the bottom of your vortex, you still find that the subsequent chambers get very dirty too. This is the very fine particles that do not have time to settle in the vortex and so they get drawn through the transfer port into the next chamber.

How the Vortex Brushes Work:

1. They physically trap the large particles that cannot pass through the close weave of the interlocking filaments

2. The filaments have a static charge that ‘grabs' any small particles that are flowing by. This charge holds onto the waste until you do your routine cleaning

3. After you have been using the brush for a few weeks, the massive surface area of the brushes becomes home to millions of beneficial nitrifying bacteria that will help to purify your water biologically

How do I use them?

Simply insert a vortex brush in the path of the flowing water. 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. With 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.
