An extensive biological and scientific program, particularly with the scientific community and in our hatchery where we have reproduced millions of tropical sea fish has enabled us to elaborate 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 analysed in order to guarantee that all important elements have been perfectly mixed. Each batch is also continuously monitored in laboratory aquatic systems containing delicate marine animals and plants, because live organisms are always the most sensitive indicators of quality.
