Today, I bought a new fish tank (8 gallons) for my goldfish. Along with it I bought a new hang-on filter. But this filter makes a lot of noise. Very much the sound of vibration. As the tank is in my bedroom, this isn't optimal and I took the filter back to my LFS
. There they put it in a tank and there was no noise.... The glass there was thicker though and I think that might be the issue with my tank. When I hold the filter in my hand in the middle of the tank I barely hear the filter, but when it's hung up against the glass it's very loud. Does my glass let through too much noise of the vibration? Somewhere I read that a newly set up tank might have too much oxygen in it and that causes vibration noise coming from the filter. Can that be an issue?
If my filter is just this noisy, can I do something to reduce the amount of noise?
