OK, I have that exact powerhead in my tank. I hope you have a bare bottom tank, or at least some really heavy gravel. If you have sand, I dont think youll be able to pull it off without having sand being blown all around the inside of your tank. There isnt a switch or level to throw to turn the output down. The only thing you can do is take the powerhead apart and trim the impeller blades down. Also, you may have a bit more luck that me because I put that in a four foot 90 gallon tank. Definitely overkill in my case.
