This is a upgrade to my existing Cardiff nano reef tank. I'm completely overhauling this tank with a new stand, new equipment, and new rock work. I also switched from a kessil 150 to a 150 watt metal halide with a Phoenix 20k bulb. Now this tank is an all in one aquarium, but this was the first reef tank I had ever ran without an algae scrubber. And to be honest I'm tired of fighting nitrates. So now i will be adding a HOB overflow box to run water into a sump underneath the aquarium where I will be able to run a algae scrubber and more macro algae. The sump will be powered by a dcs 3000 pump.
