Tetra AQ-78056 First Impressions

And SILENCE.

If that does not work, look into silicone grease so you can lube the impeller. Get it and take heed to what I wrote. However, lately I've purchased the Aqua Clear 70 and 50. Overall I would recommend this item. This filter has is a very simple and efficient design. It was perfectly quiet without any extra effort on my part. I eyedball everything and put it together with a look back at instructions.
