Awesome advice. Thanks Diana! I REALLY appreciate the level of detail. I started the deep clean process with my water change today and am going to decide on what size to go with. The 55 just doesn't have the depth I want in order to have a proper background to foreground 'ratio', if that makes sense.
PLUS, and this is daddy's fault, I left the magnetic scrubber attached to the tank one afternoon and the kids decided to help me clean. Well, they dug into the EC and brought up some nice sharp grains and did one heck of a number on my tank walls. I mean REALLY bad deep scratches. It looks like crap. That tank will probably be a grow out/holding tank for shrimp and plants trimmings to sell on eBay or something so I can subsidize the upgrade to the larger tank, filter and light. Ah the circle of life!
