I have nothing to say.....
Well.... Get the 6100s if you plan to upgrade to a larger tank, or if you want to show off. That is A LOT of flow, but they can always be turned down. They will take up a lot of space in that tank as well. I have two 6100s in my 75 and I still want more flow. I may add a wavebox soon.
Don't forget to post pics!
