NOISY PUMP

i recently changed from a large sump with external iwaki pump with not enough gph to a new 20G glass sump with internal pump. i may hate to say it but it is a rio 20hf. is this a bad pump? outside of the fact that it really pumps alot of water i hate it. i can hear it when im watching tv or outside on the porch. i know its just the vibration echoing through the walls but i really feel sorry for my fish. i put all the noise dampering plates on with rubber spacers and suction cups. the only thing i can think of is the hose i chose to use. i went overboard and used the 1/8" thick clear rubber with whte nylon braided in the center. its fairly rigid. is there a more flexible hose i can buy that might take care of this issue or should i abandon the idea of having a properly runnng sump system on a budget???

my rios always start out great then the magnet gets a bump on it and starts to make noise

what did you do with the iwaki pump?

you can try some neoprene under the pump. also make sure no return lines are touching the stand, a strip of neoprene takes care of that as well. some kind of rubber mat under the sump tank helps. to absorb almost all the sound from under the stand you can line it with a product called dyna-mat. i have a mag 7 that makes noise. i did all except the dyna-mat and it helped. i will be using dyna-mat in my new stand.

If your pump is out of balance its gonna suck.  i would put some of that spongey bio filter stuff under the pump and see if that helps.  GL
