Lighting and shadows

[tee89]

Hi R2R folks,

Currently im running my 35g Waterbox on one AI 16 HD Prime. Tanks about 8 months in now and i added 3 sps frags [1 poci 1 digi 1 birdsnest]. I noticed the polyps are not open under the stalk and base of the coral frags. I believe this is because of shadowing. Should I be concerned about this? Should I consider adding another AI HD for more spread? Parameters are stable, only issue I ran into was my dkh dropped from 9.8 to 9 when I did my water change today, so not sure if this caused some stress. thank you

You could utilize the non-flex bracket to get the fixture more centered

thank you, I will give it a shot. Will the coral die if i dont address the shadowing issue?

Die no, but you may have dead spots which should be minimal

This bracket:

You can adjust light up and down . . and . . . forward and back
