But seriously, I still haven't got the answers on what are the advantages and possible disadvantages of having red spectrum lights on our reef tank.

Sorry, I had intended to answer that last night at home... But I went and spent the whole night on Game of Thrones

Anyway, most of the appeal behind Red LED's has to do with aesthetics. If you're familiar with the Fiji Purple T5 bulb, that's more or less the effect people are after when they add this range of the spectrum to the mix.

If you're not, here's exhibit A:

Before Fiji Purple:



After Fiji Purple (red spectrum):

After:



One more:

etc, etc...

The only detrimental effect I can think of is a possible increase in algae. This assumes that:

A. The tank has excess nutrients and the addition of red light becomes the proverbial "straw that broke the camel's back", or

B. The user is comatose and doesn't crank down the red settings while addressing the excess nutrient issue.

Hope that helps!
