Jbj 6 gallon nano cube tank

[NicoC16]

I have been having a 6 gallon nano cube for quite some time now. It has been making a buzzing noise and I cannot figure out what seems to be the problem. Does anyone have any experience with such a problem or know who to contact for a fix?

Probably it's your water pump. Does it have a built in overflow sump? If so, there's a water pump that will return the water back to the tank and sometimes these things will vibrate against the wall of the tank creating a buzzing sound.

What does the overflow sump look like. I have a built in powerhead that connects to the pump.

Agree with Huffers, check your pump.
