Hmm ok possibly. My 9200 is designed a bit differently. Not sure if it's newer or older but my water wells are straight in the middle and have a 90 degree bend on the outside around the corner. No squares all the way around like this one. Is the outer part with the green rocks not designed to be filled? Mine has the holes on top of the ledges where the metal tray sits.
As usual I'm a bit late. I see now that she answered and clarified. I still find that interesting that I have a total of I think 5 wells as compared to this model.
