Christopher Greene –
The filter works well in my 55-gallon freshwater tank. The sponge stays clean and the water clarity has improved noticeably. Easy to maintain and the airflow is steady.
Rose Hamilton –
Great filtration performance. The sponge is soft and easy to clean. I noticed more active bacteria growth after a few weeks of use. Works well in a mixed community tank.
Dan Short –
Installed it in my marine tank and it handles the water flow well. The polyether foam holds up better than other sponges I’ve tried. No clogging issues after two months.
