Coralline algae will suffer as oceans acidify | Practical Fishkeeping magazine

http://www.practicalfishkeeping.co.uk/pfk/pages/item.php?news=1521 --- Corals are not the only reef organisms to suffer directly from increased ocean acidification, according to a study to be published in the journal Nature Geoscience.  Ilsa Kuffner, Andreas Andersson, Paul Jokiel, Ku'ulei Rodgers and Fred Mackenzie carried out a seven-week experiment examining the effects of increased ocean acidification on crustose coralline algae, a group of calcifying algae that is important in many shallow water habitats, including coral reefs.  The authors constructed six fibreglass mesocosm tanks were supplied with flowing sea water pumped from the edge of a coral reef in Hawaii.
