Lighting and tank questions

[Sexytang]

Ok so a few days ago I moved a few of my corals around due to growth etc. my devils hand was doing awesome where it was but moved it because it was getting to big for its sport next day wouldn’t really open much. So today I moved it back to the spot now won’t open at all. Should I move it to a spot it has room to grow and give it a few days to adjust?
And another question I have a
HIPARGERO LED Aquarium Light – Aquarium LED Lights 30W Saltwater Lighting with Touch Control and 3W Cree Chips for Coral Reef Fish Nano Tank
On my tank and keep it 100 but my nem is bleaching. I can hit the button a few times to turn the light more blue but don’t really want to drop it to low idk what to do.

The blue is what the corals like I had my set all way up to 100 for almost a year. And could figure out my stuff wasn't happy or living. So I was told by LFS to turn W20 R0 G0 and B100. And I would move the devil's hand where it has room and leave alone should open back up. Hope that helps

Do you have a local reef club? The only way to really be sure if something is getting enough light is to use a PAR meter. Local clubs often lend these around, or you can buy one for a few hundred dollars. Corals need light that helps photosynthesis and our eyes are a particularly bad judge of how much light is available in those ranges of wavelength.

I bet the coral is irritated from the attention and movement moreso than from the light. Give it some time to adjust and I bet it'll be back to how it was before.
