Emergency sos reef aquarium help

Question

Just kidding but is 500 watts of metal halide to strong for a 50 gallon tank with dimension 48x13x19? I want to grow corals and anemones but think it might be to strong. Already bought light should i downgrade. Do i have too? or is this fine

Answer 1

Reef's are very very sensitive as you may know, Having a higher wattage Light Bulb can tend to warm the water up alittle and you may need a refrigeration unit,  As for the bulb burning the reef' I'm not too sure.
