Thanks! I don’t know, but it’s almost right in the middle of two xr30 g4 on ab+ 100% and 6” under the surface. I have them in an Aquatic Life T5 hybrid fixture too. I keep going back and forth on buying a PAR meter, but have a hard time placing it in the NEED column of the many, many things I need to buy. I have too many expensive hobbies!
I hear you on that! If looking for a cheap meter then check out the Seneye. I have one and love it. Really nice for $199.
My Poison Envy is under around 600 PAR. One of my favorite pieces.
