Currently running a 6bulb sunpower with an orphek v2 and reefbrite xho supplement. Thinking about switching to leds. Found a good deal on xr15s. Thinking about putting an xr15 on the left, xr30 in the middle and xr15 on the left. Tank is 48inchs and I'm running a more sps dominant tank. What would you guys go with? Torn between keeping what I have because I have had great results and switching to leds so I dont have to pay for replacement bulbs.
