Adding A Second LED Unit Ideas On Power Settings?

[RMS18]

I just ordered a second LED unit to gain the same par from left to right in the tank. At the moment the ends of my tanks are 70-80 par less than the center. Anything I put at the ends turns towards the center. My current unit which is a AI prime is set to about 70% max. I am the overkill kind and yes I could set it to 100% and get by and everything would probably do good, but I want great, plus I am getting my toes wet with sps so I want to know I have the power if I need it. So my initial thought is to cut the power I'm putting out now in half and split the 70% between the two units to start off then increase if needed... what are your thoughts?

I'd definitely drop them to at least 30% and ramp them 1% about every 2-3 days until you see everything responding well.
