Finger coral issues

[aquariumkeeper9]

I bought two finger corals for my 10 gallon nano reef which has 4 watts per gallon of lighting on it. The tank that these came out of at the pet store had 150 watts of lighting on it. The finger corals were opened up for about a week then they closed and havent opened since. could the shock from lots of lighting to lower lighting cause them to close up and if so how long will it take for them to open back up again???

How long have they been closed? Have you tried shading them? And of course, post ALL your water parameters.

Whats Shading them mean???All my water parameters are good. My ammonia is at zero, I'm not sure about nitrite and nitrate, they were good last time i checked them. The corals are still closed and its been about two weeks. I also have a red slime algae problem in the tank which might not be helping the corals at all. Is there anything i can try to get these corals to open up???
