The filter works well in my 90L tank. Water clarity has improved significantly since installing it. The quiet operation is a big plus, and the included spray bar helps with surface agitation.

Good filtration performance. The mechanical and biological media work together well. I noticed less algae growth after a few weeks. The diverter is easy to use and keeps water flow organized.

Very effective for maintaining clean water. The Venturi system adds good aeration without making noise. Installed it in a 100L tank and it handles the flow perfectly.
