170 Substrate PAR?
Greetings all. I'm setting up a 125 gallon (72 x 18 x 22) heavily planted aquarium. I'm running a 72" BeamWorks LED and two 36" Fluval Plant 3.0. I rented a MQ-510 Apogee par meter from Bulk Reef Supply and it's reading 170 par at the substrate with lights at 100%. I will be injecting co2 but those numbers seem too high. Am I using the meter wrong? Is that par too high for plants? Should I just dim them? What is the optimal substrate par value? Thanks in advance!
