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.
Even if it doesn't do a dang thing as a filter, it's cool to watch operate. I have no doubt that it filters as advertised but seriously would consider buying one for the show alone. It took a couple of hours to get the balls moving, but since then it's been rolling right along.
Cannot day much about the filter yet, as I’ve only had it for 2 weeks. Took some time before it would start tumbling the media but now is pumping full strength. Unsure why I’ve read noise complaints in reviews...this thing is quieter than any other filter I have. So far, so great! Highly recommend. Shipping was stellar.
