CBF & BF-6000 Koi-Teich-Filterschwämme

I'd been washing my old foams for so long they were practically falling apart, so these replacements were overdue. They kept their shape immediately after installing, which was a relief since the last set sagged after just one rinse cycle. Solid value for keeping the pond water clear again.

The replacement foams slid right into my existing filter frame, and they’re noticeably denser than the old ones. After a single washing cycle, the pond water cleared up faster than I expected.

After a few years, my old foams were completely flat, so these replacements fit perfectly and restored my filter's performance. They are dense enough to catch the fine debris without slowing the water flow too much.
