how to obtain Par Rating?

[lewismw]

How can i get the current par rating for my tank? Is it just based on the information at manufacture website from the combination of bulbs or is there a way to measure the different depths?
:confused:

You need a par meter with a waterproof sensor. Most folks uses this meter.

Does the Apogee give you LUX or PPFD in addition to PAR?

This particular one only gives out par or umols

They run around 250ish. My local reef club has one and any member can borrow it.
