Well, after much research, my 2.5 gallon pico reef in finally set up! I have 1.5 inches of live argonite, and I'm going to pick up some live rock today! I have a 3 gallonair powered filter running on it, mostly for oxygen and water movement. My light is a 10 watt multicolour LED made of 3 bulbs(red,blue, green). I made a plastic cover(looks kinda tacky, but works) and the light is sitting directly on top of that, only 1 inch above the water. I'll be posting regular updates as I add stuff, so follow along!I'll probably have lots of questions as I go too, so your input will be greatly appreciated!
