Your tank is amazing! I am in the process of purchasing/gathering everything I need for the 150 that I am picking up in a few weeks.
At what point did you stop vacuuming your sandbed? I do a little bit each week on my 32, but I that is only because it is smaller and harder to keep balanced.
Thank you!!! I stopped vacuuming it when I started doing auto water changes using a DOS module. Probably about 2 1/2 years ago or so
