I have been running an icecap 4-54watt T5HO retro over my 75 gal. for about 8 monthes now. but yesterday switched to 2 - 400watt 20k XM MH. i was wondering what would be a good way to acculimate my corals to this new light. i am gonna do the start of running the bulbs at a certain number of hours a day then increase it after a wile till i get to my regular lighting schedual. but what would be a good start? 2 hours a day and increase the lighting 1 hour every 3 days? or start off more than 2 hours?
BTW the MH are 9" above the water and the T5's were 3" off the water.
TIA
