Bio Tek BTM3000 par meter

[dmcoates]

I have recently purchased a bio tek marine btm3000 par meter. I love it so far. I am currently running the worldwide Coral eco-tech schedule. Basically AB+ for 7 hours (19k) then the schedule changes, turning off all the white Spectrum for the last 5 hours.

What type of correction factor would I need to do for a somewhat accurate par reading.

I was thinking 1.2 or would need higher once all the whites are turned off.

Thanks for any input..

I've always added 10% to the LED readings. I know I remember reading it in a couple of places along time ago so that's what I've always done. Please understand, I'm not say it's the way to do it in all situations. I'm curious to see what others have to say.

The Guy at aquarium specialty told me to use 20% with the blue spectrum. I am assuming once at the all blue side I would use 20% but maybe just 10% when the whites are at 24%. But that still pretty blue at 19k.
