Hello all. Just moved up to a 40 gallon tank from a 10 gallon tank. Only a few corals and just two fish from my other tank. Had to cycle the tank with livestock in it not good. Lost a tuxedo sea urchin and a blue damsel. The guy at the LFS said I might have issues but needed to do something because the old light from the ten gallon tank were toast and they had no replacements. SO far so good still have AMMO but doing water changes. I am glad they had no replacements for the old tank
