Product Description
The Koralia Evolution 850 gph is one of Hydor's new and innovative wavemaker and circulation pumps for small reef and fresh water aquariums. The Hydor Koralia Evolution design and technology guarantees a continuous and powerful water flow which can be directed freely thanks to the special sphere-shaped connection to the exclusive combination suction cup and magnet support. High performance, low energy consumption and quick and easy maintenance. Includes cable protector and is ideal to use in tanks with urchins, triggers, puffers and parrot fish. Unlike the non-Evolution Koralia pumps, the Koralia Evolution can be connected to a Wavemaker. Please note, if you are using the Hydor Koralia Wavemaker, you will need to use one of the Koralia 12V Controllable Powerheads.

There was a problem filtering reviews right now. Please try again later.
I would highly recommend these pumps to anyone considering them for a saltwater tank. They really pack a punch, in a good way!
Unit #1 ran for (3) days on Hydor's own Smart Wave timer. The magnetic impeller continuously fell out of the groove and lost the ability to spin. Upon further inspection the bushing was swelled and barely allowed the shaft to spin. Amazon was top notch as usual and shipped out a brand new unit right away.
Unit #2 ran for less than 24 hours before it stopped responding. Power to the unit was fine, and I did in fact switch outlets to eliminate that as an issue.
If the impeller was removed and then reinserted the unit would usually spin back up. I did not buy the smart wave unit and these power-heads so that I have to babysit it every 15 minutes.
I am trying to get in contact with Hydor right now as I am told there is a modified impeller. Hopefully they have a fix for this issue as I cannot expect Amazon to keep sending out units until I get lucky and one works.
Update 9-24-12:
I adjusted my rating to 4 stars after getting the unit to work correctly for quite a while now.
The bushing in the rear of the unit within the housing itself required replacement. It was causing the unit to seize up as described above even though all signs pointed to the impeller swelling and causing the issues. Replacing that one little ceramic bushing turned this unit from a loser to a fantastic addition to the tank.
The 4 star rating is only due to the fact that this pump has performed flawlessly since the part change. Not a single hiccup!
Hydor did take a while to get back to me, but they did send out a replacement impeller as well.
Now this is not something that should have occurred on multiple brand new units that I received and the 4 star rating is quite a change, but I cannot imagine my tank without the flow of the Koralia.
Bigger than say a Jebao or MP10 but you save some bucks and granted they are not wave makers. Hydor does show these as being used with their wave maker controller but I have seen that they will click every time the speed is changed. I have seen conflicting literature that these can or cannot be used with a wake maker. Even from the manufacturer literature.
If you want to use them as they are designed, I can wholeheartedly recommend them.
