Hello reefers today I rented a PAR meter from BRS. My plan for my reefer 170 is a SPS dominated tank. The attached picture shows PAR numbers with light at 90% using a diffuser (XR30 Blue). Highest point to waterline is 10 inches. What are your thoughts on the numbers? Good range or should I bump them down a little?
