Highly-concentrated ionic strontium solution. Provides strontium, incorporated by corals, clams, and other reef-building invertebrates into aragonite, the mineral that is secreted as skeletal material. Contains no unwanted organic material such as EDTA, gluconate, or polygluconate, and is free of phosphate, silicate, and organic material. Over 50% stronger than most competing products. Formulated by a marine scientist. |
