Hi. Maybe you guys can help me. I bought EcoTech Radion XR15 for my 20 gal. Fusion Nano. It is 24" long. I was set to buy Mounting Bracket. Looks nicer that suspended from Celing in my opinion. But I have some doubts now. With Bracket Light is set about 8" above Tank with no adjustment. If I hang it from ceiling I can adjust hight to whatever I'd like, right? What would you guys recommend? Thank's in advance.
