HOB stands for hang on back and they usually call powerfilters HOB filters. I dont know if i'm blind but they never said the size of the tank... do you have any idea of how many gallons it can hold? It sounds like a nice deal because an ehiem is about $100, the UV is around $50, the hood is probably $100, and the tank is around $100 or more depending on size and the stand is $100 and that is the average prices usualy of the equitment new but the stand might be a bit more and the tank also. So i guess you found a pretty good deal, that is if everything works
