So, Ive decided that while Im moving the tank into the new house, Im also going to switch up my lighting. Ive been running an ATI Sunpower (8x80w) for the last 2+ years and while I love it, I really really want to use some Radions. Since I have the room in my budget to do so, I picked up 3 - XF-15s with the intention of running them in a hybrid T5 fixture. One the 525, Im thinking I may need a fourth to fill out the tank completely for SPS. Has anyone else run this kind of setup before?
