Review on 🐧 MarineLand PRBW150B 150b Bio Wheel Assembly Penguin Filter Parts: Top-Quality Components for Your Aquarium by Kate Korte

I've had no luck with these bio wheels. This is the third car I have and now it has stopped spinning again. I did the second one a few months later and the last one was less than two. The bracket that this wheel sits on is clean, as are the small pins. The only thing I can think of is that the wheel is unbalanced as it always stops the same side up. I change the filter media once a week so water flow isn't the issue. As soon as I run out of filter material, I will switch to another filter system.
