The BioFoam inserts work well with my Fluval AC20. Water clarity has improved noticeably after a few weeks. The dense structure holds bacteria effectively and the mechanical filtration keeps debris out of the tank.

I’ve used this filter for about two months now. It’s easy to install and the water looks cleaner than before. The biological filtration helps maintain stable ammonia levels.

Great value for the 3-pack. The foam holds up well and doesn’t break down quickly. My tank has been running smoothly with no noticeable filter clogging.
