I would but it all depends on what you are trying to keep, I found that the small fuge in the back did not really function that well and meet my need's so I added the one in the bottom. I would suggest it you would not regret it, it woud only make the system that much stronger and versatile. You could keep the balls in the back and add the fuge in the bottom and you have a ton more options for skimmer,ato's and in my opinion all the way around a better way to go for the system. as far as lighting I am using a single par30 5k led from home depot and it grows like a beast I harvest every three days and take it to my LFS stores for credit. If you do get it you will also need a esshops nano-overflow, and if you need it I will send you pics and instructions on how I installed mine. Shoot me a PM if you need advice or part numbers i am more then willing to help you get it set up. The esshops rs-75 is the only store bought one I found that would fit I looked for about three months online and in store they were either to big or a wet dry but the rs-75 fit like a glove but you have to take the doors off to get it in. Either way hit me up if you need anything.
