Hi guys. I am at a loss. I don’t know why my dianthus’s are all closed up and they’ve been like this for weeks. Everything else seems to be mostly happy even my SPS parameters are as follows.

Magnesium 1380
Alkalinity, 8.2.
Phosphate .05 ish
Nitrate 20
For the rest, see picture attached I do not have my calcium reading right now.

I had an algae bloom not sure why, but everything else looks happy even the more sensitive corals
