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.

Tetra AQ-78056 Final Thoughts
5 minutes.
My tank is nice and clear and my fish are much happier. Fill up the media slot with water until it's full. I use Marinelands refillable cartridge for extra carbon on the extra slots. Typically just below the flat part of the outlets. You can't really tell though, and the filter is working great. You'll want to pull that water from the bottom. My baby turtle even loves it so much he won't let go.
