Is my par map adequate for SPS acroporas?

[Miami Reef]

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.

I 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.

Should I lower lights or higher intensity?

Not sure how much I can help given that I'm relatively new to SPS myself, but a little more info might be useful. How deep is your tank and roughly how far from the water surface is that 360 measurement? What PAR meter are you using?

I’d say higher intensity. But as I said, it’s not only light.

Yes, increase your intensity or better yet, add some T5 or LED strip lighting.

I played with lights more. I got around 280-350 par in the higher areas of tank.

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.
