Does anyone have a light meter that we could borrow for an afternoon? I don't know much about pur and par, but it is time to learn.
May I borrow a light meter

OK - so the reason I was asking about a meter is this: On our 180, there are some stout cross braces across the top of the tank. Unfortunately, the two of the banks of light we have (Solaris) line up with the braces. Each brace comprises two pieces of stacked glass with a total thickness of 5/8". I'm trying to figure how much transmission loss I will have - probably a lot.
