I am looking at building my own LED
fixture however I am curious how much wattage it should have. Its a standard 55 gallon tank and I am thinking I'll be adding corals later. Currently I have a T5 fixture that houses 4 54 watt bulbs (2 actinic and 2 10k) for a total of 216 watts witch seems standard for that type of fixture. I really like the way LED
's light the tank thus the "upgrade". Also, I like the idea of not having to change the bulbs or forgetting for that matter. So, when planning on using 3 watt LED
bulbs, how many total watts are ideal for corals so that bleaching isn't an issue?
