Mitras PAR readings

[Aqua-Digital]

Many thanks to one of our Australian users for this info -

Readings taken with an Apogee PAR meter, all pumps turned off in my tank. Tank had a water change yesterday. To keep the readings consistent I placed the meter's sensor in the tank and took a reading in High Efficiency mode on the Mitras then without moving the sensor changes the lights to High Output mode and took the reading. This was repeated at each level so the results are comparable with my situation.
