sea swirl or wave2k?

[crusty1]

I have a couple of wave2ks in my 180g and I love them for the amount of water movement that they make. There are a few issues with them; they require a fair bit of real estate, can be noisy, are ugly, and require some maintenance. To take care of the ugliness I made a great big live rock wall to hide them behind.
I decided on the wave2ks for my tank as I had to tear one tank down and put the other in its place, in the course of a few hours. The wave2ks served my purposes well.
