does a great job at keeping the filter clean....
A simple solution to help your filter work better. Keep the food where the fish can eat it, Not rotting in your filter.
I prefer sponge filters because they AR a very good filter versus their cost. I have about a dozen or so of these filters, at least one in every freshwater tank, a medium sized Sponge Filter in my saltwater quarantine tanks, and now several in my Axolotl tanks. You get great filtration plus the added benefit of aerating the water. Overall I recommend sponge filters like these over any other filter money could buy.
It is working great with my shrimp
Good product. The best service in the business!!!
