What is PAR and how much do we need?

[Dana Riddle]

Interesting. So - it was always my impression that bleaching meant 'turn white'. Are you saying that the tops turn 'white' and the shaded areas remain 'colorful' - or are you saying that the top areas (under the higher par) a lighter colored than the bottom? Would you be able to post a picture/example? Thanks!

So sorry for my tardy reply. Long, long story. See this video at about the 14 minute mark.

Thank you so much for the link, and the reply Mr. Riddle ( for solving them lol ) You answered quite a few questions for me. The interaction of all the applications was an education in itself. I had already decided to purchase an Apogee MQ-510 Par meter as I mentioned. Luckily I believe that I have the flow correct in my yet to see coral tank. I feel much more positive about proceeding now thanks to your huge investment of time, and money. I hope people appreciate that you shared this wealth of information so freely. I know I would have set my PAR way too high If not. Regards: Wally
