I use one 750 in a 90g tank and can point it almost right at corals with out hurting the coral at all, while still preventing detritus from building up. The draw backs are the thin slots can get clogged, wont always flow in the right direction when turing them on, and start to break down after a while (about 2 years of running). For the price though i like them a lot and are great for starting tanks.

Worked good for a while. By Mike on 10/22/2012

I bought 2 of these (750 Model) a while back to try as a wavemaker setup. They worked ok for a while but then started to run in reverse at different intervals and then to the point where they would always run in reverse. With them running in reverse it has caused the round part in the screen, in front, to break away on the both of them. If I turn them off, 9 times out of ten they start in reverse. So now I just try to leave them on all the time, when I use them. I am going to replace them with another brand.
Buy it. Seriously. By fissy guy on 10/17/2012

I bought this pump (the 750 model) in March of this year. I was worried due to the cheap price that I would get cheap quality out of it. ...let me tell you, you can take it apart fully (which I have done several times for cleaning and inspecting, as I do with everything else in the tank), and it is still performing now almost 8 months later with just the same power it did on day one, and hasn't given out on me once. If it ever died, I would buy another in a heart beat.
Bottom line--- IT LASTS, and IT WORKS VERY WELL.
Over 3 years and still going By amber on 10/16/2012

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 10/6/2012

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 9/21/2012
MJ's Custom Aquarium Water wouldn't recommend this product to a friend
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.

Good flow By Earl on 9/13/2012

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.
