Acans not opening fully??

[kayraw]

For some reason my Acans just don't seem to open up all the way.

I have many other different types of corals in my tank (soft, lps and sps) and these are the only things I seem to have problems with.

There's no other corals around it and all parameters seem ok, tested with redsea

Can anyone help me?

Alk 9dkh
Cal 450
Mag 1400
Nitrate 0
Phosphate 0

Flow on acans: low/moderate

Placement: 2" from sandbed
And 2" to right of led

Lighting: xr15pro
Settings: ab+ @ 70%

On the left side, I'd say cooking it with light. Try shading and see.

i'd say more flow. my acans like moderate/high flow.

Try more flow, less light.

I was thinking less light too as people have told me that my schedule is a bit high intensity... I moved the one on the left off that rock last week and it didn't seem to change so I moved it back. It's been this way for a good few months now even though I've had sps frags turn into full size colony's

Have you change to leds recently or are acans recently introduced?? If yes, be careful with aclimatation...I lost 10 different acans when I changed to leds from t5 years ago in an lps dominated tank
