Aquarium Advice Activist
I have 3 HOB filters currently running, the Aqueon 30 in my sons bedroom is actually pretty quiet, My AquaClear 110 is so quiet I have to look at the return to see if it is running. My Aqueon 55/75 however is very loud (note the motor is not loud, the sound of falling water is however. Not a big deal as it is in the basement until this winter when we sleep down there on weekends (probably dream of waterfalls and wet myself in bed)
