Good sized By Shane on 1/8/2011

I have a couple Hydor pums - this one and a couple of the smaller ones. This one really puts out the muscle - there's a lot of flow. At this flow level there's several good pumps to pick from but this one is right there w/the others. It comes with a good solid magnet to position it on the glass. It is a very straightforward setup.
Great! By Jamie on 12/31/2010

The evolutions are head and tails above the old Koralia's. Added 2 750's to 2 existing Koralia 4's in my 90. The flow is much broader, no vibration running or on start up with my timers. Awesome pumps! I will be replacing the existing Koralia 4's with new 1400's a.s.a.p
Great little pump! By Tim on 12/12/2010

I purchased this pump for a dead spot i had in my 90g reef tank. I have it hooked up thru my Reefkeeper Elite on my wave timer. Works flawless no clunking on and off... It is completed hidden from view behind my rock work....
Great flow for the price! By Luke on 12/6/2010

I have 2 of these along with a 1400 in my 55 gal mixed reef. I think they are a great value and would recommend to anyone on a budget. They have very low power consumption and are a lot smaller than the older Koralia's. One of mine did cut in and out of operation, but I moved it and now it works fine (this is the only reason I gave it 4 stars for performance).
Good flow, and quiet! By Swerve on 10/25/2010

This pump is excellent. Small in size, big on flow and ergonomics. The ball-and-socket magnetic suction mount works well. I'm using three of these in a 150g tall tank, great water movement through the rockwork.
Big Value, reasonable price! By Kyle on 9/27/2010

Hydor has done it again! Smaller frame that the Koralia 4 but more flow. Silent with the new design and no spindle to worry about caking up. Oh yeah, only 6W. Home run!!!
compared to the tunze nanostreem.. By Erik on 8/29/2010
Erik would recommend this product to a friend
I have used both the koralia and the tunze powerheads. The Hydor koralia really has the best value because they are significantly cheaper and seem to do the job. I do think that the tunze nanostreams are more attractive, built better and easier to aim the flow. I have never had to call hydor before but the one time I called tunze with a warranty issue they solved my issue with a 2 minute phone call, I was really impressed. I would use the koralia again in any tank where i was trying to keep things cheap but always go back to the tunze on my show tanks.
5 stars By The mule on 8/29/2010

I was using only my returns and some maxi jets for flow and the tank was doing "ok" . After adding four of these to my 90 there is a night and day difference in the tank. My small cyano problem literally disappeared overnight and I have never seen it again. All of the coral polyps are extended beyond what i thought was possible and the fish play in the flow all day long rather than just sitting there or moving slowly.
Poor Product By Brian on 8/21/2010
Brian wouldn't recommend this product to a friend
It is noisy, and poorly / cheaply made. All plastic including the prop shaft which was not straight on the one I got. Pump would barley move any water, it spent more time stopping and starting and ratteling. You get what you pay for! I have 2 of the magnums also and have been happy with those. I was enticed by the adverstised low power consumption and higher output listed for the evolution models. Other net postings I have seen complain about the same issues.
