What can I use this for?

[discretekarma]

I had a Koralia burn up on me and even though me and the rep agreed that it was probably my fault, the agreed to send me a new Koralia 4 at no charge to me. I received the power head today and in the box was a Hydor Aqua Color. It's a blue LED light. It is submersible and seems pretty cool. It seems like a moon light but you can put it in or out of the water. How should I use this?

Also, can Koralias be used with a wavemaker?

 

Thanks
