Do I need to turn up my Kessil?

[Waffen06]

I have two tanks, a 20 nuvo with a Prime HD and a 60 cube with a kessil 360we. I have never gotten much growth from corals in my cube. I recently moved some zoa frags from my cube to my nuvo and theyve opened up so much more. I run my kessil at 70% max, being a 24" deep tank is this not high enough? I worry with several corals on my sandbed such as hammers, torch, elegance, zoa frags and trumpets that they are not getting enough light? I dont have access to a par meter. I never ran my kessil higher as I didn't want to promote extra algae growth. Should I raise the power or look at upgrading lights

What do your the corals look like that you mentioned? Do they look healthy? How high is the 360 above the water?

Corals have always looked okay, just not much growth. They definitely open up more and look better under the prime. The 360 is about 8" above the water

I would consider raising the intensity slowly. You could do 5% week. Try reaching 85% intensity while monitoring your corals. 24” is a deep tank, but that’s a powerful enough light for it.
