Rated 1 out of 5 by Roryrory Noisy and low flow
Unit has been used twice for mixing salt water, cleaned in fresh water to help with corrosion. It sounds like it's going to explode and its flow rate it's...well lacking for a pump. I would not recommend this pump to a friend.

I wonder who rates these pumps. I bought this for my 30 gal. I bought it as per the rating on the box. The 400 is better suited for a 20 or a 15. Good powerhead but not for a 30gal tank. I need another to get water flow the way it should be.
All my powerheads are Marineland because they are a good product. Trouble is the ratings are not correct. Go a step above than what the box says.
