what powerheads.

+1 on koralia powerheads. Iv had both and I believe that koralia far exceeds the maxijets. Plus the magnet on the outside of the glass will insure that they never fall and create a mess or catastrophe in your tank

 

Here's a cool way to go for your size tank. I'd get 2x300 Aquarium Water Circulation and Powerheads: Hydor Pico Evo-Mag Circulation Pump

and add a Hydor flow to both http://www.youtube.com/watch?v=byGPtB1fDnQ&feature=endscreen&NR=1

At the moment I'm running 2x240 Koralias on my 26g bow fronts. I love the flow of the Koralias. However as I've grown in the hobby I've learned that to have the ability to rotate your flow through out your tank is by far the best thing you can do for your corals. With the above mentioned, you'll not only get good flow but you'll get random, wave like flow. I wish I would have found this in the beginning of my tank

 

think im going to get those. hopefully my lfs has hydro ones

 

Smart choice, great flow options and less money
