lps help

[nanonøkk]

ok so i’ve been noticing that some of my lps corals have not been opening up fully such as my frogspawn my duncan and then my blastomusa. the only thing it could be is lighting but here’s some pictures of them and some perameters
ph 8.2
dkh 8
nitrate 2
salinity is 1.024
and i dont have test kits for any of the others and here are some pictures
oh and all the corals eat except the duncan i didn’t see him eat today when i tried to feed him.

They don’t look horrible, have you changed anything lately with the tank? How old is the tank?

the tank is 10 months old and i’ve slowly been moving the light to turn on and i’m moving the lighting over by 10mins every two days
