"When I first purchased this tank I was extremely excited. I liked the look of it, and thought it would be a great home for my betta fish. I purchased three of these tanks, and sad to say they were a waste of a money. Yes, they do look very good on the box and even when you put them together. The problem however is that the pumps stopped worked and no water was flowing through the filter. :( I contacted the Tetra company and explained to them the problem. They kindly sent me two more pumps and motors for the tanks that were having issues. Well, then the third went out. And sure enough, the two new motors they sent stopped working. I have contacted the company once more to explain to them my true disappointment in the product and how I feel it was a waste of my money. I have replaced the two tanks and soon to be third with a Top Fin aquarium which has had no problem. Had I known then what I know now, I would have purchased the Top Fin aquarium before and saved a good $70-$80 dollars. Unfortunately, no more Tetra products for me."
