I’ve used this filter insert in my 55-gallon saltwater tank for over six months. The water clarity has improved significantly, and I notice less algae buildup. The foam fits perfectly with no gaps, and the bacteria colonies seem to be thriving.

Great mechanical filtration with solid biological performance. I replaced it after two months as recommended. The tank water stays cleaner than before, and the flow is steady throughout the filter.
