I have a customer tank whose owner wants to make the jump to LEDs. Bulb replacement time coincided with the chiller crapping out, so it's probably the smartest time to do it. I've done a few retrofits of the Blueline VHO strips (most of my customers have decorative canopies that the lights have to fit in), but have absolutely no experience with the pendant style fixtures. The tank is 60"L x 24"W x 25"H and is lit by 8 x 54W T5 HOs. Corals are a mix of SPS (Caps, a couple of easier Acros) and LPS (Euphyllia, Favia, Plerogyra) which all show good color and grow nicely. The customer is interested in both the Kessil A350 and the Radion XR 30 units. I'm going to remove the top panel of the canopy to allow the lights to be suspended at whatever height I need. My question is whether or not I can get by with just 2 of either unit and still maintain even coverage, or whether 3 will be required. TIA!
