Here is where I'm thinking the 90g aquarium will be set up: There is lots of space between the window and the kitchen counters. This spot will ensure we can enjoy the tank while eating and preparing supper, something we've always enjoyed with the 34g tank. This is also the same outside wall where my RO/DI system is now living. I am considering putting the sump in an equipment shed outside at the side of the house. Gotta figure that out still. The 90g will have to wait a little bit as we want to get the house painted. What looked like pristine walls in the open house turned out to need a good coat of paint.
