You’ve most likely heard of Purple Up, the product that some aquarists use when they can’t seem to get any coraline algae growing in their saltwater aquariums. Besides being a very popular product, Caribsea, the manufactuer has been touting that they recently were issued a patent for Purple Up. It seems that getting those pink, purple and other colors of coraline algae are worth a patent. Because of this Caribsea is having a big promotion wherein you can get your hands on a bottle of the purple stuff. CaribSea is telling us that they are giving away over $16,000 worth of free product, so go join their twitter feed and hopefully you’ll get your own very bottle too.
