"I love the BiUbe!! Unlike other posters, my pump is very quiet as long as it's not touching anything, which is not a problem. It's very stylish and easy to clean. The heater adapter made for it works very well, so I have tropical fish in mine. My local petco carries the filters, but I find they're usually on sale on petco.com and I just order 6 at a time to get free shipping so it actually saves me a trip to the store."
