how much light wattage am i going to need to properly light a 40 gallon reef? i want to have the flexibility to have different types of corals and anenomes. the problem is i want to get a retrofit kit for my existing hood but i have a truvu tank which means the hood is only 24 inches long. would a CF light kit work okay? also what do the types of lights mean i.e. 10000k, 20000k etc. and what is the best type? thanks
