On average how deep do hqi lights penetrate. I have a 55 gal from water surface to glass bottom is 18 inch on or about. The hqi set up I’m looking at has two 150 watt 10k lights. I'm thinking that with those two bulbs that should be more then enough light to penetrate to the bottom and take care of the lighting needs of coral and btas of any sort even maybe a carpet. Any thoughts on this light set up
