OK, another newbie question: I just got my "new" ATL-1000 heating properly, and it's rolling away doing a dummy run when I notice the tanks aren't really immersed in the water. I noticed before that the longer tank doesn't sit right on the rollers I bought this along with 3 1500-series Jobo tanks. The store also had some larger 2500-series tanks, but the manager told me these were for the other, larger, processor they were selling. Did I get ripped? I just saw Jobo's website says that, with a cog, 1500s can be used "on all processors equipped with a JOBO Lift (except ATL" (and then it cuts off.) Is that correct?
