If you looked at the PAR meter thread, you might have seen where I told Frankie G that it's useless.
I know him personally, so I felt I could make a response of that nature on the forums.
We spoke on the phone today about the subject and I've come to the conclusion that the PAR meter is nothing more than a toy that's fun to play with.
At one time I was excited to play with it and I took all sorts of measurements with all sorts of tanks and light systems and then I passed it on. Many people did the same. But yet we all failed to do one important thing:
Validate the results.
Sure, we got some numbers here and there, hither and yon but there's simply never been an attempt to define the light requirements of any given coral. I told this to Frank today and I'm convincing myself that it's true.
What say you?
Toy or Tool?
