Review on 🐠 Enhance Your Aquarium Filtration with Marineland PR1940B 170 Bio Wheel Assembly Penguin Filter Parts by Richard Singleton

Revainrating 2 out of 5

I immediately replaced it and the new one works GREAT at first and then slows down and stops.

As can be seen in the picture, material separation. I believe this is a defect. Because the water gets trapped and the wheel doesn't turn. I swapped it out right away and the new one works GREAT at first and then slows down and keeps stopping. The instructions say it still filters even when it's not moving. That's not true, my water turns yellow if it's not moving properly.

Pros
  • Filter accessories
Cons
  • Some difficulties
