PAR levels for certain corals?

[ChrisIC]

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

I think those PARS are good.

Even 40 for the Lobo? It seems fine though, growing, although slowly.

Lobo is a real slow grower anyways.
If everyone looks good, I’d not try and up that 40 as you will also change the PAR for everyone else.
It’s amazing how corals can adapt.
When everyone good, never change again.

I'm always a little bit scared of changing my light settings so I will leave the lights as they are, it's easier to move the a coral to a slightly brighter spot if needed more light, but they all look OK as to me. Thanks
