Why do I need Vortex Brushes:

Vortex chambers work well for settling heavy waste but struggle with lighter particles. You might notice that despite collecting a lot of waste at the bottom, subsequent chambers still get dirty. This is because fine particles don't settle in the vortex and are drawn into the next chamber.

How do they Work:

Black Knight brushes trap large particles with their close weave interlocking filaments. The filaments’ static charge grabs small particles flowing by, holding onto the waste until you do your routine cleaning. Over time, the brushes’ massive surface area becomes home to millions of beneficial nitrifying bacteria, purifying your water biologically.

How do I use them:

Simply insert a vortex brush in the path of flowing water and you'll be amazed at the waste collected in a short time. You can strategically place a brush around the transfer port or build a barrier above the inlet and below the outlet. This allows heavy waste to drop to the bottom, forcing the remaining waste through the brushes. Coiling the brushes around the outlet ensures water passes through, creating a complete barrier for optimal waste collection and biological filtration.

Vortex brushes can be used in as many chambers as you need. Leave some room in the first chamber for settling, but subsequent chambers can be filled with these brushes.

How do I maintain the filter:

Cleaning frequency depends on the filter size, pond size, and system loading. With a lightly loaded system, cleaning every three weeks in warm months is enough, but heavily loaded systems may need twice-weekly cleaning. Brushes can be cleaned in situ by draining the chamber and rinsing with pond water, or taken out, cleaned, and replaced. Using chlorinated tap water reduces the brushes' biological effectiveness temporarily.
