How do you run your ebay LEDs?

I'm just curious as to what percentage you run your channels. Im currently running 50-50 and I'm scared to kick them up too high. Tank is 18" high with LEDs sitting about 10" above water surface.

I run mine blues 45% whites 25% with a 16 inch high tank 5 inches above the water level. I just have zoas and mushrooms though. The par on my tank with this configuration is around 80 at the bottom.

par meter will not produce an accurate reading of the par level for the LED fixtures. with that been said, i run by blue at 100% and white at 75-80%

The only time the readings are inaccurate is when you measure close to the surface.

I don't really use it. I turn up the light slowly and see how my corals react. I only put the numbers up so you'd know how much light it produces at my percentages.

How tall is your tank and how high is your fixture above the water surface?

here's the article that enunciate the difficulty of using a Par meter to measure an LED fixture, especially full spectrum LED.

Aquarium Equipment: PAR Meters and LEDs - How Accurate are the Measurements? A Comparison of Three Meters and Lux to PAR Conversion Factors for LEDs €” Advanced Aquarist | Aquarist Magazine and Blog

many forum members exhibit the same frustration when trying to measure the Par level of the LED fixture, whether on the surface, substrate, or somewhere in between
