The problem with the second option is the seller is telling you up front that it is not in working condition, and that the tanks are not in good shape. It could be the deal of the century, but it stands a better chance of being a never ending project in patience and perserverance to get it setup and running properly.
we know where we are putting it already, its alot of room and hes blocking his stairs off with it. his house has a very weird lay out we are trying to correct with a tank.Oh yeah, another thing you might want to think about is how much room does he actually have for a tank to sit? That could narrow the playing field down a whole lot.
i think i might employ him to help me with setup!That is what is weird about the add. He talks about having holes in the stand for plumbing and things that match the side cabinet. From the pciture it looks like it might have a corner overflow, but it is a little hard to tell. The sump would give you extra water volume and a place to hide the equipment. It may need a sump and just doesn't have one now, or he may have used the side cabinet to hide the equipment in. Since he tore it down he should be able to tell you how to set everything back up and get it working properly.
