Would a 24 inch photonV2 be overkill for a 20”long 18”wide 20” deep cube mixed reef with montis, gorgonians, clam, leathers a BTA and some lps? Depth to sand bed is 17.5 inches. Right now I have a 70 watt halide with a 14K bulb and I feel I might need more power, although everything is growing, even a monti at 12” down on the rock.
