i have no idea what light to purchase for this tank.i'm pretty sure i want metal halides=250 watts.i would perfer not to hang a light over the tank-but i can go that route,would just have to put a board in the ceiling above the tank,which would suck.i have a 48in coralife professional series fixture aqualight pro-2 150watt and 2-96 watt and led's but i think this light would look silly.plus i think i should aim for bigger halides.i need some help.
