Important Sizing Information
The Green R-Matala roll is intentionally manufactured approximately 1/2" to 3/4" larger than the listed diameter to ensure a tight fit inside your filter tank. A snug fit prevents water bypass and improves filtration efficiency.
Measure the exact inside diameter of your tank before ordering. If your filter size falls between available sizes, choose the next larger size and trim it down for a custom fit.
Example: A 22" R-Matala roll is typically closer to 22.5" actual diameter.

What It Filters

Cleaning Instructions
For routine maintenance, use a water pump and flexible hose to flush pond water through the media while it remains inside the filter tank.
If heavily clogged, remove the R-Matala roll and rinse thoroughly using pond water whenever possible.
Avoid using chlorinated tap water if the media is functioning as a biological filter, as chlorine may damage beneficial bacteria colonies.
Important Note About Hair Algae
Green R-Matala is not recommended for filtering string or hair algae because algae can become tangled within the media and make cleaning difficult.
For ponds with hair algae, we recommend placing a layer of Black Matala before the Green R-Matala to help capture larger debris first.
