Good afternoon everyone. After many years i have decided to jump back into the hobby. Its an understatement to say the the equipment has really come a long way. Which leads me to my very novice question (forgive me if its been asked before). I am looking for LED lighting options for my soon to be reef tank which is 48x18x20. I'd like to do fish and soft corals. Amazon has tons of items, and its a bit overwhelming sifting through it all. Does the the old 4 watt per gallon rule still apply?
