Got this tank a few weeks ago from @Coral reefer for my school classroom, but major problem for me - it doesn't fit through doors without a complete breakdown each time! Not to worry for me, I was able to get another 150 gallon for the classroom, but my effort is to your benefit as I gave the tank a mild clean and the sump a citric acid bath, both are in great condition. For pickup in Los Altos for free, stand has wheels so it is easy to transport!
