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

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.
