I had a JBJ30RL for a while, great tank. Neat little trick is you can put both media baskets on one side, leaving room for a nano skimmer on the other. Also the pumps seems to be prone to build up. I had to take mine out and clean after about 3 months after one of them just stopped working. It turned out to be some buildup around the magnet. Also the glass lids are super fragile. I chipped one of mine just gently putting it down for cleaning. Other than that, it's a great tank and you'll enjoy it.
