I too had a not-so-great experience with JBJ (don't worry I'm not totally dissing JBJ or "plugging" Aquapod, just sharing an experience). After all the research deciding between the Aquapod and Nanocube, I went with the Nanocube, thinking the horror stories of a leaking or cracked tank would never happen to me. I put my sand in, began to fill it up with water, and a small stream of water came pouring from underneath. I thought, maybe I spilled a little water when filling the tank, but nope, there were two places on the tank where the seam was not sealed and it was cracked. The tank arrived in what appeared to be perfect condition, no marks on the box, etc, and I removed it as carefully as humanly possible as to not stress any parts of the tank.
