CUP-305 Replacement Pond Filter Foam

My waterfall pump was barely pushing water, but after swapping to this cut-to-fit foam the flow came right back to full strength within minutes. The open-pore texture is visibly coarser than the old mat, which lets the water pass through without constant clogging.

I’d been fighting a slow trickle from my waterfall for weeks—swapped in this foam and the flow doubled instantly. It slid right into the slot without any trimming, and the water clarity improved noticeably within a day. Exactly what a tired filter pad needed.

The cut fits my unit perfectly—no trimming or wrestling to get it seated. Water flow through the fountain is noticeably stronger now, and the pond surface stays clearer for a full week after install.
