Upgrading Power Heads - 28 Gallon Nano

[chromakey]

Good Day:

I was thinking about upgrading the two Hydor Koralia 425 GPH power heads in my 28 gallon Nano Reef Aquarium.

I am trying to choose between the Tunze Turbelle Nanostream 6015 and the Ecotech Marine Vortech MP10W ES. I haven't seen the Vortechs up close and at $300 it is a substantial upgrade over $40 for the Tunze.

I am looking for a clean look for the aquarium but I am a bit unsure about the really benefits of the Vortech.

I guess if I do upgrade down the road the MP10 would be useful in a slightly larger tank.

Thanks,
Michael
