Instant Ocean contains all of the major, minor and trace elements necessary, ideal for all types of aquarium. It does not contain nitrates or phosphates. An extensive biological and scientific program, particularly with the scientific community and in our hatchery - where Instant Ocean has produced millions of tropical sea fish - has enabled us to eleborate and refine a formula that fulfils the needs of captive marine organisms. Each ingredient used in the composition of Instant Ocean is carefully selected and tested. Each batch is anaylsed in order to guarantee that all important elements have been perfectly mixed. Each batch is also continuously monitred in laboratory aquatic systems containing delicate marine animals and plants, because live organisms are always the most sensitive indicators of quality.
