WOW!!! You are a really handy person. Beautiful stand and canopy. I know the title stated FOWLR. But if you add a few colorful and easy to maintain corals to the setup, you will be surprised how beautiful the setup would look compare to FOWLR.
I started with a 300g FOWLR. Afte a while the bare LR looks kinda boring. So I added a few easy to maintain corals ( RBTAs, Blue/Green mushrooms, some frogspawns) to the setup. It really made the setup much more beautiful, and it doesn't really cost me any additional work to maintain it.
