Tank is a mixed reef with sps corals.
I have 4 ai hydra 52 HD’s 12” above water. All blues, violets and UV is 120% and Reds, greens, and whites are 20%.
12 hour light schedule with 4 hour ramp. It gets full intensity for 8 hours.

And flowI would say mostly no, or maybe- in the top part of the tank.
Acros like 250-350 PAR, ideally. Sometimes more.
Also, it’s not only a matter of light but water chemistry too.
I’d say higher intensity. But as I said, it’s not only light.Should I lower lights or higher intensity?
That should be sufficient, but as others have said you might want to consider adding T5's. I have a 135 that is 3' x 3', it's 24" high. I chose the Hydra 32's so that I could get 4 of them for more even coverage, they are mounted about 18" up for good spread and overlap. Although I have plenty of light I'm still finding that there are allot of shadows so I ordered some T5's to fill it in a little bit.I played with lights more. I got around 280-350 par in the higher areas of tank.
