ai prime light recs

[caveman28]

Alright so i recently got some macros for my 20 gallon macro focused tank, and i'd like to know some people recommendations for light settings for optimal color and growth of macroalgaes and softies. I only plan on clove polyps and a toadstool coral-wise and have the tank outfitted with 2 ai prime 16hd reef lights.
I'll attach a screenshot of my current settings and want you guys to let me know what i should change or what recommmendations you guys have for them to grow nice and healthy. Thanks in advance!

Is there any reason to have 2 and turn them down so low? I'm just curious since one prime can easily light the tank.

I think that renting a par meter would be the best way to know how to set the lights without cooking the corals.

I just got 2 because i had some shadowing and had a really good deal on them. They're set lower because i was told if i was adding the second i should be careful its not too much light or i could provoke a nuisance algae bloom or cause coral burning.
The corals will be at mid level of the tank about 6 inches from the surface.
