i currently have a 4x39w t5 light, half 10k/half actinic, on my 30 gallon reef. The tamk is 36 x 12 x 16 with a 3" sand bed. So the deepest the corals would be is 13" and most would be on rock above that. I have GSP, xenia and finger leahers. I am thinking about upgrading to an led fixtures. How, many watts would I need to allow me to keep LPS and SPS? Any. particular brand you suggest? I don't necessarily want to buy the most expenxsive one available, just decent quality for what I want to keep.
