Finally someone has made a moving bed filter that runs off of air and fits into our aquariums! We don't have to try and DIY them anymore. These units are great because they come with an easy to remove intake sponge and the media starts moving from day one. Unlike k1 media where it can take days to weeks for it to start moving. Taking out all the guess work and making it simple hook up to an air pump and getting all the benefits of oxygen in the water and a super charged bio filter.

If you've never seen this before, they're so great because they constantly rub against each other and cleaning the medium as well as only letting the strongest bacteria survive. With oxygen traveling through, the oxygen rich water combined with strong bacteria handle large amounts of ammonia in comparison to other types of filters.

We feel this filter is best suited for 20 gallon tall and larger aquariums. One Ziss Bubble Bio can handle up to 40 gallons by itself. Best combined with a sponge filter or hang on back as this will handle your biological load in the aquarium and some mechanical, but if you want crystal clear water you'll want to add a mechanical filter like a sponge filter or hang on back to the mix.

Love them!

They were super easy to install and took a day or so to start moving but now they are working perfectly!

Ziss filter

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.
