Underside of coral bleaching

Is there anything I can do about the shaded areas of a coral that are bleaching? Running 3 AI primes on a 4’ tank

How are your parameters? Par might be a little low with only 3 AI primes. Any idea what your par is?

No clue on par. Working on getting a meter and better lighting soon

Alk - 9.5
Calcium - 500
Mag - 1500
Nitrate - 7
Phosphate - 0.06

Cal and Mag are high but they’ve been stable with those numbers so I just let it be

some XHO or similar strips will add filler light if that’s what you’re looking for light wise to fill in the gaps and have those pointed at an angle instead of straight down
