My entry will be my 21"x12"x9" 1/2" thick acrylic desktop nano. Last month I had a heater not shut off and cooked the whole tank, and lost all of the coral in the tank. So I'm restarting it and at the same time as the contest. I haven't decided what exactly will be inside, some kind of lps though and no fish. For the first time in about 2 years I'll be running a filter. Since I downgraded to the 24g, I haven't used a skimmer or filter. I looked over different filters and had a tight budget, I decided on the Fluval C2. It's still fairly new to the market and I'm intrigued to see how it performs in saltwater. For lighting I'll be using a Nova Extreme 2x24w (UVL 454 & UVL Indigo Sun).
