Heard a lot of great things about Reefi Duo Extreme. It's a bit too big for my 20 gallons nano tank (display tank dim 18"L x 14"W x 16"H)), isn't it? I saw a photo of Reefi Uno on it's Facebook group (too bad I don't use FB). Could someone shed some light on it's specs, price $, and estimated availability? I am using AI Prime and would like to try something new, high tech (in terms of functional and control-ability), comparable and even better than AquaIlluminum and Ecotech Radion.
