I've had this tank for five years now. While it's a great tank it has many flaws. If I could go back in time I would have gone a different route. One being the stand. These have a habit of corner cracks and jbj won't warrenty without using their stand. The stand is crap. The back chambers, all were different sizes due to not being careful and I had to take them all apart and reglue to fit equipment in. The pumps are crap, throw them right away and get something that works. The tank is deep but not so wide which makes one kessil 360 fairly worthless it would seem. There is a place in the back chamber that is impossible to reach, I finally blew it out and the amount of crap it trapped was the main reasons for my nitrates. All in all it's served me well. In fact the first one they shipped was broken, I had a piece of glass made and siliconed it and use it for freshwater. So bonus?
