Hey all, I am using an mq-510 par meter. After watching my lps struggle on the sand bed, I took a par reading. Why would my par be 255 center of the tank on the sand and 220 center of tank on the rock? The tank is a RedSea p650 with 3 Radion blues.

Thank you. Just picked up a few diffuser To see if they helpLEDs focus light differently than T5s and there are definitely "hot spots" where they overlap.
My par was 300 next to the glassAs stated it can be the rock is high enough that it doesn’t get the overlap from other fixtures. Also possible if measurement is close enough to the glass it’s getting increased par from the reflection off the glass. That can add up to a surprising jump in some cases
