I bought their display tank, so I highly doubt it. I already seperated all the pieces and have to say, jbj did a horrible job to begin with. Its visible where the silicone wasn't sealed correctly in a couple spots on the bottom and that's where it was leaking from. I'm going to start resealing it today in phases...the bottom first and then then back tomorrow. Using black silicone this time which I personally like better. I don't use an ato, but I can understand what you're talking about...
