Good luck mate. Don't be surprised if the divider gets moved. I seem to have to re-adjust the divider every week as the rays manage to dislodge it and i am not happy with the gaps that are left with the suction cups etc that hold the divider in place as i am paranoid any pups may get to the other side if they are born when i am not about. So i plug the gaps with filter foam but the rays push and blow so hard on the divider that things get moved!
