The Bio Foam fits perfectly in my Fluval FX5 filter. It’s easy to install and keeps the water clear. The porous structure traps debris well and the water quality has improved noticeably after a few weeks.

I used this with my saltwater tank and noticed a significant reduction in particulate matter. The filter runs smoothly and the bacteria colonies seem to be thriving.
