I don't know if they are all that loud or if its just this one. She had the setup for a few years - so it may just be age related. I got her a 20G tank and a aquaclear filter and took her 10G and the aquatech. I have an tetra 10i and an aqueon quietflow 10 in my bedroom - both are pretty quiet but the aquatech one made such a racket. I think I may go with a sponge filter for the 5G as well since I do have an airpump laying around.
I think people may see sponge filters as being out dated. Plus I have only seen the actual sponge filter for sale online. Airpumps and tubing I can get anywhere but walmart, petco and petsmart don't seem to carry sponge filters.
