Hello. I finally signed up today although I have been lurking for a few years now. I have had saltwater tanks since the early 80s. I also have had goldfish, koi, cichlids and discus fish at various times. I currently have two mixed reefs, a 120- and 90-gallon tanks. I set them up probably about the same time i started lurking on R2R so a couple years now. Always something to learn with reef tanks. Keeps the mind young! I appreciate the vast amount of knowledge and talent I see on R2R and hope to learn from all.
