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.
Delbeek and Sprung's "The Reef Aquarium: Science, Art, and Technology, Vol. 3" has quite a lot of new info on the use of sulfur reactors and sulfur beads. I don't have the book handy, but he even recommends adding a layer of them to the substrate if I remember correctly.
Many roads to true...
