Help! Second time I am dealing with major fluctuations in PAR meter readings, for instance a range of 70-150 or 105-280. What could I be doing wrong?
I have adjusted the sensor eyeball direction in diff locations with no better results.
Most problematic tank has Kessils and quite a lot of shimmer. Do you turn off return pump? Or circ pumps if they disturb the water surface?
