Help me tune my lighting

[Ghost25]

I have a Waterbox Cube 20, currently lit with Kessil A80 on the left and AI Prime HD16 on the right. The Kessil is on from 10AM to 9PM (No controller just a timer). I've had some issues with slow growth and SPS bleaching and I want to make sure my light is ok. Leaning towards the idea that it may be too intense. I got a PAR meter and measured a few points at 4PM (when the Kessil is on and AI is at its plateau).

Any suggestions on adjustments? Too long, too intense, wrong spectrum, etc?

Your numbers are great. I’d look elsewhere. Highly unlikely spectrum is the problem

Cool, thanks

Leave where you have it. Ai prime will have a higher PAR but you have them balanced
