Having issues with brown button polyps!

[jackstir34]

Ok I am new to the game so I decided to go with the hardiest corals. I was told button polyps, and fire zoas, green zoas, and brown and green mushrooms. I have a 29 gal tank with 2 10,000K bulbs and two T5 Actinic in 24 inch ballasts. water params are PH 8.2, dKH is 12, nitrites 0, nitrates <1 ppm, ammonia (even with ammonia rock) tests at about .5 ppm, phosphates 0. I dipped my corals in Iodine to rid of some bristles and ghost shrimp. the buttons however were not open even before that. They have been closed about a week now. My fire zoas, green zoas, and mushrooms are all doing great, any suggestions?

Based only on the photo and the fact that everything else seems fine I wouldn't be concerned. There bulbs appear fine. I'd just give more time as there isn't really isn't another good option. Were they dead you'd know it.

These are the good corals and frags in the tank
