Hh guys. I've been measuring my PAR levels at the sand bed today and am wondering they are high enough for some of my favourite corals. The reason I checked os because I've noticed that the Cynarina and Acanthophyllia aren't expanding quite as much as the used to and I think they have darkened in colour a bit. In the picture the Acanthophyllia is closing up for the night, it expands more than this during the day. Does this sound OK...
Acanthophyllia 100
Cynarina 80-90
Fungia 60
Trachyphyllia 80
Lobophyllia 80
Lobophyllia 40
