Coral-shop is a relatively new line of reef aquarium additives and products with an emphasis on maintaining balanced and stable reef aquarium chemistry. Coral-shop doesn’t necessarily deliver on any new groundbreaking products but their labeling and clear instructions make it easy for European reefers to decide which of the three product lines is best for them. The Platinum Reef line includes three additives, it is the most basic additives and Coral-shop has some explicit guidelines for it’s use a stand-alone 3 part solution or in conjunction with a typical calcium reactor set up. The Marine Line steps things up a bit with up to 6 different additives for a little bit more control of marine aquarium chemistry in a method that closely resembles European balling method. Finally the Coral-Shop Profi-plus line takes their concept to it’s most extreme iteration with up to 15 additives for deliberate micro management of reef water chemistry. The Profi-Plus additives include four major elements, six minor and trace element additives and five dissolved organic matter (DOM) additives for near OCD level control of everything you could ever want to squirt into a coral reef aquarium. The broad line of coral-shop additives may seem excessive but we really like the clear-cut, beginner to expert level of additives that coral-shop provides. Coral-shop emphasizes performance and strong value for the cost of their additives but since we’ve never used it, we cannot testify whether coral-shop additives are really good or whether the cost of coral-shop additives is less in the product and more in the fancy bottle and the marketing. Perhaps our euro-reefing brethren can chime in with their experience using coral-shop additives.
