They are expensive. I have the nano I won at the frag swap up and going. I added black sand and some semi live rock that was in a cooler in the garage. So far everything is going good just playing the waiting game on the cycle. Today I ordered the AL Sol Super Blue Nano LED light. I am really looking forward to it arriving and getting to try it out. I ordered the touch screen controller too. This allows for many different options and settings for the light. I will post some more pictures after the light arrives. I went a little expensive on my "cycle" fish but hey I have always wanted one so i splurged.
