The Atlantic Water Gardens replacement brush panel for the PS4600 and PS4900 Pro Series Pond Skimmer provides fresh mechanical filtration brushes for the skimmer's debris separation chamber. Brush panels in pond skimmers trap fibrous debris — algae strings, plant fibres, and fine particulates — before they reach the main skimmer basket. Regular brush replacement maintains mechanical filtration efficiency and prevents debris from bypassing into the pump chamber. Mechanical Pre-Filtration for a Cleaner Pond The brush panel acts as the first stage of mechanical filtration inside the PS4600/4900 skimmer. Brushes trap suspended debris that would otherwise pass through the skimmer net and reach the pump. Over one to two seasons of use, brush bristles flatten and lose their interception efficiency. Debris passes through flattened brushes more readily, reducing overall skimmer performance and increasing the frequency with which the pump impeller must be cleaned. Replacing brush panels annually at spring startup maintains optimum two-stage mechanical filtration performance.

Slide out the old brush panel and discard it. Slide the new panel into the same position, ensuring it seats correctly across the full width of the skimmer chamber. Replace the lid and confirm normal operation. Inspect and clean the brush panel monthly during the active pond season. Ideal for maintaining Pro Series skimmer performance in Canadian koi ponds and water gardens.
