PF Pond Filter Foams

Took me a while to realize my pond was getting green because the foam inside was packed tight. Cutting it open showed exactly how clogged it had gotten, and swapping in a fresh piece brought the water flow back to normal instantly.

I noticed the water flow in my fountain had weakened, so I swapped the foam and it's been running strong again. The pond clarity improved within a day after the replacement.

The foam fit perfectly into my canister and the water flow was back to normal within a day. I’m glad I caught it before the pond turned fully green, since the pressure drop was the only clue.
