My advice, downgrade, keep the best of everything you have and put it in a nano. A 20g with sump or similar you can deck out the nano with TONS of equipment that will make it less maintenance intensive system with less cost and give yourself a break. Chances are you will get the bug again for a bigger tank in a couple years. But there are a lot of things to enjoy about a nano some people never upgrade.
