Now we have five 400W metal halide for this pool, and sun light is stronger than winter, the color of some SPS corals is great, but about 60% SPS is still in brown or dark color, corals begin to grow, all the fish is healthy, many living alga (Gracilaria and Ulva) and purple seaweed has been feeded every day.
