Hi everyone. I have haf 2 zoas and gsp in my tank almost 3 weeks. Under a dual t5ho light. I added another dual t5ho light 3 days ago. So now theres 4 t5ho. I have my lughts come on at 10am go off at 7pm. So i had my first light on regualr schedule and had the new light come on at noon to 3pm to slowly add in extra light and not kill anything. Was that still too much is what im wondering. My gsp was fine first day amd zoas too but yesterday and today they arent opening all the way. The gsp barley had any green grass sticking out amd its usually fully out amd waving everywhere. Should i leave new light off for a while till they get bak normal and then add new light even less than 3 hrs first time. How much should i add firt day and then each following day? This osbmy first corals so i have no ideal...i hope i didnt kill them:( my water parms are right on track cal 420 ph 8.1 salnty 25 kh 8 i dose everyday. Nitrate 0 amm 0 nitrite 0 use rodi water. 65 gal system with 20 gal sump. Any help appreciated

Light shock, because t5s supposedly have a very high par for the first 50 . GSP are super tough, those things can be closed for months and then open back up . Most zoas are also tough, but some can melt under too much light . You can pre burn your bulbs for 5 days 10 hours per day outside of your tank then put them on and start with 2 hours adding 15 mins each consecutive day.
