make sure you have a 9 volt battery, this meter did not come w/ one...We are breaking out the LUX meters today for reading at the water line.
I had my Orbits at 100%blue and 50% white. Running the Hydra's I have so much more color with out having to run all the blue to pop the color of the corals
2PM and no clouds in the sky gives me a reading of 120,000 LUX. The tank lights just kicked on, but ramp up for 1.5 hours. Will post reading at 3:30. No work for 36 hours or so. Time for tank maintenance!!!!!!
