A new issue of Advanced Aquarist Online Magazine is available as of today with tribute to the late great Peter Wilkens, the godfather of basic reef aquarium keeping as we all know it. Whether you keep a Berlin Reef, Ecosystem Aquarium, Algae Turf Scrubber or filter free nano tank, we as aquarists owe a great debt to the pioneering work Wilkens provided towards our basic understanding of keeping marine invertebrates in aquaria. Wilkens was the first to discover the need to replenish calcium through adding Kalkwasser, the benefits of protein skimming and the use of pelletized activated carbon to clean aquarium water. Many of his other great contributions to the global hobby of reef keeping can be read in his full memorium on AA. Other noteworthy articles in AA this month include Dana Riddle’s continuation of coral reproduction, Ken Feldsman’s second article on Total Organic Carbon in the reef aquarium and Micro-Ecosystems by Jay Hemdal.
