Don't know if this is legal or not, but I just found this review in the lighting, filtration, and other equipment section. So I thought I could share it here.

Hydor Koralia Review
I just got my new Koralia 3 pump today and if your anything like me you know I had to take it apart to see how it works. I have a tunze nanostream 6045, and my plans were to use the tunze on one side and the koralia on the other. I wanted two tunzes but I cant find another one, so I got the koralia.
The pump is a little bigger than the nanostream, but only a little bit. I do like that you can take the whole pump apart and replace only the broken piece if something should break. So if the ball joint should gets lose you can take it apart and replace the O-ring to fix it. The koralia is kinda cheaply made, even the prop feels a little thin, but for $40 what could you expect. I think that Hydor could have made the pump a little smaller, especially the shroud. I like the nanostream's shroud better. The magnet, well its no where near as strong as tunze's, or sure grips magnet. If you take off the suction cups the magnet is alittle stronger. I had it on the back glass on my 55g and you have to hold ithe magnet while you pivot the pump, until the suction cup sticks. So the suction cups do work, but Im wondering in 6 months will they get stiff like all other suction cups? Thankfully I am using it on the side glass where its alittle thinner. By no means will the pump fall on the back glass, it does hold it there, but to pivot you have to hold it. I kinda wish the magnet was stronger, but Im sure it would have cost more. Hopefully the magnet is stronger on the 4 pump since it bigger and will be used on bigger tanks. The one good thing about the magnets is that they are much easier to move than tunze's.
So my final word is that they are a nice pump, cheap, and move alot of water. For the price they are great, but if you got the money I like the nanostream better. Although, you can buy 2 koralias for the price of one nanostream, so if you only have $100 I would get 2 koralias instead of one tunze. Two pumps are better than one. So I think more people will be using the koralia due to the price.
