unhappy coral

I’ve had my small 20 gallon cube running well for a year and everything has done amazing and growing, but over the last couple of days a couple of the corals have been unhappy. My Goni and hammer won’t open, and the foot on my hammer is getting smaller. Also one of my purple polyp corals won’t...

I have had this trumpet for a long time, originally in a pretty low light 5 gal, until about a year ago i moved it to the big tank. Was happy for the first couple months but its condition has slowly deteriorated after a magnesium spike, and magnesium is still a bit high. Moved it to 60 par low...
