Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I think it's a matter of personal preference really. I know red wouldn't look natural to me... two of my tanks have blue although one is a bluer blue and one has white. I prefer the white or light blue the best, I think it's easier to see critters in a soft white moon like glow over a colored one.
I just installed the blue leds about two weeks ago, and they look really cool. Kind of erie at night with lots of shadows. I see more of my peppermint shrimp and emerald crabs during that time.
I got the light kit from Aquatic Obsessions in Avenel.
