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 ran a fish only with live rock tack for four years (in the 90s mind you) with stock lights on a 20g nano tank. i did not have a ton of algae, but had almost no coraline growth. i had two damsels, 1 camelback shrimp, and a maroon clown, and was running it with a hob filter and no skimmer.
