I was at my other pet store when i saw a 55 gallon tank with the stand and a started kit. It was the kind of stand where it could hold another tank at the bottem. So it was $150.00 and i was thinking about getting it for my new freshwater tank. Do you think it is a good buy? I thought it was a good buy because in petco i saw a 30 gallon tank with a started kit, without a stand for just as much.
