I have a custom sea life 48" 4x65watt fixture. I need to buy replacement bulbs for my 75 gal reef tank/ all sorts of different corals. Right now it came with 2 10000K and 2 actinic. When I look to buy I see daylight bulbs of 10000K and 6700K. What would be best. Also I see 460n actinics and 420n actinics and one that combines 460n and 420n in the same bulb. What would be best. They are 65watt square pin. Thanks
