I purchased several sps corals frags and have had them in a prop tank with a 175 watt MH. They were in the prop tank for about 6 weeks while I finished up my 180 gal reef tank. The 180 gal reef tank has 3 - 400watt MH's and 8- T5's. My corals lost some color while in the prop tank. I want to acclumate them to the brighter light (400watt MH) without causing bleaching, etc. I'm starting out with the 400 MH at 3 hrs per day for two days and then adding 15 minutes every two days until I work it up to 8 hrs per day. Does that seem reasonable or is there a better way. I appreciate your help. Duane
