Brightwell Aquatics NeoMarine Salt Mix creates this ideal marine environment for aquarium inhabitants by providing all major elements, all non-conservative minor and trace elements, and elements known to be utilized in the production of biological pigments (biochromes) in precise natural seawater ratios. Elements are provided by individual salts (no seawater evaporite is used) enabling consistency in each salt mix. Contains no detectable ammonia, nitrate, phosphate, or organic substances at standard specific gravity. It dissolves completely to create crystal clear water.
