Has anyone ever modified thier Juwel tank stand to be able to take a decent sized sump. I'm tempted to come away from external canisters and do things properly but unsure of the complicity. I also dont want to dismantle my tank if at all possible. Previous idea was to put two 12"x15" tanks in the stand, one in each cupboard and either use an external to transfer the water between each one. Alternatively, I could drill the sides of each of the sump tanks and run a couple of large diameter pipes between them, keeping the water level constant. Any help appriciated.
