1) I'm thinking of changing my lights from 14k to 20k (same wattage). Do I need to acclimate the tank? For how long - a week?
2) Do corals change color with changing light temp? Not just in how it appears under the new light temp, but do corals actually undergo a color change? And if I go back to the original light temp, would the color go back to its previous color?
