par meter

Hey guys I think our club borrows out a par meter right? If that’s so. Can I grab it from whoever has it at the expo? I really only need it for an afternoon so I can map my tank out. Or I’ll rent one from somewhere close figured I’d ask here first. Point me in the right direction! Thanks...

I busted out the par meter for a test and was interested to see how much... or little par is on some acrylic surfaces. First is par near the bottom of my tank. Second is the meter facing straight down over a black surface and then a white.
