I purchased an apogee mq510 par meter for my eshopps m130 build. I tested my current setup, a 60g cube 24”. Two kessil a360xe and 4 ati t5 bulbs. I use kessil reflectors to narrow the beam and reduce light spillage. I tested my par in center of tank. It said 972. Most my acros getting 550 to 900 par. I decided to use the less narrow reflector. Now I’m around 550 par in the peak areas. Most everything from 6” up are above 350 par. Bottom is 220. I run the lights at 80%. Should I reduce intensity? Corals look fine. I’ve had to move some lower in the past because I thought they might’ve started bleaching. Fine now though. I never would’ve guessed par was that high.
