Review on π 6-Pack of Koller Products Small Replacement Filter Cartridges - Optimize Your Search! by Amanda Castillo
These filters last a long time.
I bought these for both of my goldfish tanks after replacing them with a larger tank. They last much better than the last ones I had and I can change them for much longer. The water in the tank stays clean and even if I take these filters out and expect to need replacing they still look great. Would buy again.
- Double-ended polyfiber line for removing fish waste and other debris.
