Doable. I could do anything to the panels. Then it would match my walls. I think I'd prefer something that stands out rather than blends in.
I've already ordered magnets so I'm definately doing some type of panel job.
On to the next order of business: Planning the sump area
Below is the diagram I just came up with. This utilizes two aquariums drilled simply to make a bigger sump. I'd be looking for tank dimensions 30x12x16 if there is such a critter. I don't think I need any baffles except near the end so that water evap would be more noticeable in that last section.
