Over 3 years and still going By amber on 10/17/12

I bought 2 of these when I set up my first tank. Since then I have tried adding different brands over the years when I wanted extra flow but they all died or had issues while my original Koralias are still kicking with zero issues ever.
I take them out and bang them in the sink to remove bulid up and while I know I shouldn't, still they keep on blowing. They are silent and dont run hot which makes them perfect products.

Easy to install with good flow. I bought two to push water around my rock. Strong enough for LPS corals and not harsh on the fish.
Don't waste your money on suction cup pumps. By turtleghandi on 10/7/12

I have both the 550 and the 1050 pumps. I got them to replace some cheap suction cup pumps that kept falling down. Both are working great. They have stayed right were I put them (thanks to the included magnet) and I don't detect any stray voltage in the tank. The packaging (on Hydor's part) could be a little better. The parts were just sort of rolling around in the boxes. Its not really a problem since none of them appeared to be damaged, but it makes them seem cheap and I could see how it might result in some damage during shipping.

Satisfactory for small tank By MJ's Custom Aquarium Water on 9/21/12

Pro's - magnet is awesome, it is going nowhere. Unit is very quiet, I don't notice it turning on and off. The quality of the build should last.
Con - I have a 550 and even in a 34 gallon tank it is weak. I have a much smaller one that generates more current. A little unimpressed with it's power.

I have two of these, one on each side toward the rear of the tank and they keep good flow throughout the tank. I supplement them with two nano powerheads on the sides toward the front of the tank. Corals are thriving and growing well.

Good for the price, but there is a catch By Joshua on 9/3/12
Joshua would recommend this product to a friend
I currently have 3 Evolutions, 2 of them work perfect and the other has to be "bump" started. The price is right compared to the next best thing, the Vortech. You can buy 10 of these for the price of 1 of those, so for the hobbyist, this is the way to go.
GOOD PUMPS FOR THE MONEY By Tom on 8/12/12
Tom would recommend this product to a friend
I bought these pumps because they were alot cheaper than others I looked at. They are a bit bulky in size but they work good. They are quiet, magnets are really strong. They are hard to adjust the angle of flow but they also stay at the angle you put them at so a good trade off. I also use them to stir my saltwater in my mixing bucket which they do really well at.
