I have 2 Radion g5 Blue over my frag tank which is 12in deep,lights are mounted on the radion arms.I rented the apogee par meter from BRS and at full power im getting a reading of about 200-300 at the bottom of he tank on the racks. Does this seem accurate? I thought the radions would push closer to 400+ in a 12in tank.I grow sps and if the readings are correct i would run the AB program at 100%
