They were super easy to install and took a day or so to start moving but now they are working perfectly!
3rd one I’ve ordered, love them. Hoping they come out with a smaller size.
Works great once established, very economical, will definitely be adding one to every aquarium.
Couldn't recommend this filter enough! Not only does it work great and keep my tank much clearer than it did when I was running a sponge filter, it’s surprisingly fun to watch as well. Ridiculously easy to maintain. If you’re remotely considering this filter, buy it it’s worth it!
When it was first installed it would not tumble at all. After a few days I noticed it was upside down and it immediately started working as it should. The good side of it was that the bacteria fully established and my fish aquarium is sparkling.
