Mine are pretty close to this too. 67% max for blues but my rocks are 12” under water at their highest.Nothing crazy blues and purple range from 20%-60% through out the day. 20% at 9, 40% at 11, 60% 12-5, then back down. Red and green 10%-20% from 11am-3pm. White 20%12pm-4pm. Lights are on 9am-9pm, T5’s 11am-4pm. My rocks are pretty high I was getting 400par at the highest point. Hope this helps. My acros went crazy after the acclimation.
