This is a genuine ASM replacement outlet pipe foam designed to restore the performance of your protein skimmer. The foam insert fits directly into the outlet pipe of compatible skimmer models, serving the critical function of breaking the surface tension of the exiting water. This process effectively reduces the amount of microbubbles that escape into your sump and main display tank, while also dampening the noise created by cascading water for a quieter aquarium system.

Specifically engineered as part number SP-PS-ASM-1009, this outlet foam guarantees a perfect fit for ASM G-4x, G-5, and G-6 protein skimmers. As an original equipment manufacturer (OEM) part, it ensures that your skimmer operates exactly as intended by the manufacturer. Over time, the original foam can degrade, clog, or become less effective, making this simple replacement a crucial piece of routine maintenance to uphold your skimmer's efficiency and the overall clarity of your aquarium water.

This replacement foam is an essential item for any aquarist currently running an ASM G-4x, G-5, or G-6 protein skimmer. If you've noticed an increase in microbubbles in your display tank or if the water return from your skimmer has become louder, it is likely time to replace this component. Swapping out the old foam is an easy and cost-effective way to bring your high-performance skimmer back to its peak operational standard, ensuring a stable and pristine reef environment.
