Ensure the supplement is reef-safe and follow dosing instructions. Avoid overdosing, as it can lead to imbalances and become toxic to corals and other invertebrates in your tank. Some other element additives may already contain strontium as a byproduct of process. Dosing strontium in a 1:100 conjunction with calcium, as they work together in coral growth. When using calcium supplements, know that excess strontium may enhance the loss of carbonate alkalinity. Don’t mix a strontium supplement directly with any carbonate supplements. Calcium, alkalinity, magnesium and potassium levels all must also be maintained within the proper ranges as they all work in conjunction with each other and strontium. When mixing strontium, it is important to dissolve the powder in a portion of the volume of distilled water, then add dissolved solution to the remaining volume. Each reef tank is your work of art, and the ideal strontium level can vary based on many factors, such as your coral type, coral density, and your water parameters and husbandry practices. Strontium is depleted from your water column through various processes, such as coral growth, skimmers, and other filtration methods. Clams, snails, shrimp and invertebrates use strontium to build, molt and maintain their shells and exoskeletons. Rapidly growing stony corals, particularly Small Polyp Stony (SPS) corals like Acropora and Montipora, must have consistent supply of strontium for their growth. Strong calcium consumption, is an indicator that strontium is also being consumed at a quick rate as it's incorporated alongside calcium in skeletal growth.
