Corals wont open

Hi I was on the same boat when I started my tank.
My suggestion is to buy Bio-Spira (benificial bacteria) that instantly cycle your tank. Poor the whole bottle in the tank. The first couple weeks, watch out for ammonia. After that, get Natural Nitrate Reducer to eliminate Nitrate. You can also buy sea water in cans to boost up the system.
I don't see enough lighting in the tank as well.
All the additives I said are available at PetSmart. They are cheaper than any other store.
Good luck!
