Coral problems

[brianle0612]

Hello everyone, im newbie in this hobby so please help. All the corals were happy and fully open so far . Since 3 days ago I noticed that corals were not happy and not open up like before. I lost 1 bicolor angle fosh due to ich problem and trying to feed the fish w clam. Other than that everything r normal. Im wondering whats the main reason to
Make them not happy ? My tank is waterbox 105.4, my ph is 8.3. Alk is 9. Any advices will appreciate alot..

+1 on then pictures and other water parameters.
would also help to know how long you’ve ran the tank for and if you dose cal-alk and mag

sorry for missing all that info. I stoped by the LFS and asked them for th test and here is all the numbers as you see on the photo. My tank is running for about 8 months and I am dosing only alkalinity manually once/week. Not dosing calcium yet. As you see in my tank that the leather coral and 2 gornipora not open at all. What would I do now ? Thank you all

will go on a limb and say it’s probably not enough cal-alk and mag in your system. It’s always either that or lighting/flow

I think I know whats the problem makes my coral not happy. Its calcium. Anyway thank you all for your advices so far.

Your ammonia is high as well as your nitrates and phosphates; likely causing issues, especially the ammonia; assuming that the test is accurate.
That said, you should test for ca and mg. Along with alk, those are essential for coral success.
I will say that goniopora are not easy corals and usually do better in well established ecosystems. Even with stable parameters they are not easy to keep.
