This is my downsized tank. It's a 20" acrylic My Reef Creations cube. I didn't want any bracing for a clean look. There is no sump. I have a Tunze Nano Reefpak, a maxijet 1200 and an Aquamedic Oceanlight pendant 150w 20k. That's pretty much it!
As far as livestock goes, I've got two fish - a scorpion and a dwarf fuzzy lion. The tank is LPS dominant. I have mostly chalice corals in the tank. There are some softies and two or three sps.
