I'm a newb. I'm ordering a inno marine 38 g nano tank. There are 4 options I believe on the led light. There's a 10k 14k 20k or dual spectrum. I don't know the difference. Please help. They are all the same price. I'm gonna have multiple types of coral and a few small fish.
I have been out of the game for a while, but I believe if you want to grow some corals and you also want to get some good color to pop. I would go with the dual spectrum.
The higher the number the more blue they will be...blue brings out the color, but the lower k's will promote more growth.
