I already have a 6000 running in my 36x24x24, but want to add another. Planning to go full sps, and I am considering a 7095 with either another 6000 or 6100. Which would you suggest? I recently rescaped to have vey open space between rocks, and hope to place the stream midway in the tank's height, resting on some tonga branches, so the streams will be directed into the "valleys". I am inclined to go with the 6100 owing that I can tune them down, but not sure if you would advice otherwise.
