HELPPP corals not opening

[Zbass]

The Video below is what my corals are looking like. My issue is that is the most my corals will not open. it's been doing this for months. right now my parameters are DKH=8.6 Ca=420 MAG=1150 Nitrates=8 Phospates=0.05. now yes my mag is low now. so two issues. whennparameters where stable when this all started. I have been on here many times trying to figure out what's going on. ive had suggestions to do water changes, change light schedule, check par, salinity. I have even did about a 80 water change the other day. and put new rocks in there. but something is affecting all my corals EXCEPT my scolys. I have had birds nest, anemones, ducans, every thing but acros in here. and they never will fully open. I have two tanks currently and this one is a 15 gallon and my other one is a 65 gallon and use the same water and salt (reef crystals) from both and I have done ICP test and nothing unusually. so what the heck is going on? 2nd issue is im try9ing to raise my MAG but it doesn't mater how much how dose I can not get it to go up. why would the mag not change ? please help me im really struggling with this tank. Fye all the peramaters were fine when this started 2 months ago. the mag issue started a week ago.

Can you tell us about your lights? What kind of light at what intensity on what size tank? I'm not seeing any algae growth anywhere, it looks so clean, I'm not sure the light is high enough
