PAR Numbers

[Chrisz]

I took par readings in my tank, from what I understand I need to multiply my readings because its under water by 1.25 right?

Not with the mq-510. The stated number is the par.

Thanks, after some digging I finally found it

*The MQ-210X and MQ-510 Underwater Quantum Meters already apply the immersion effect correction factor to the meter readings through the meter firmware. Additionally, the SQ-420X and SQ-520 have an "Immersion Setting" that applies the immersion effect correction factor to the sensor readings through the ApogeeConnect Software. These sensors do not need post-measurement corrections applied to their measurements.
