Works in conjunction with outside rim filter and UV sterilizer. Bacteria filer works great with a combination of all three.
The filter itself is great at doing what it claims to do. However, it is extremely loud. I wish Ziss made a way that the bubbles exiting the filter were smaller. They are loud and there is a constant blurp, blurp blurp. I tried everything I could think of to quite it down to no real avail, maybe Cory can figure out a hotrod solution.
I have a sponge filter and UV sterilizer in tank, but I wanted to add this filter for additional filtration. It took the media a few days to start tumbling completely, but now a steady roll! Fun to watch...even my fish watch the action...LOL!!! That is all great, but the additional filtration for their tank is definitely 5 stars!
Seems to work really well
Easy to set up, needs lots of air and time to get going, and makes big bubbles which are very loud. Does NOT work for a bedroom.
