This calculator estimates the imbalance of selected major ions in saltwater caused by the repeated dosing of
any of the four two-part recipies described in Randy Holmes-Farley's
Reefkeeping article.
The calculator assumes that all of the calcium and alkalinity added to the system is consumed by biological
processes. Additionally, in line with Dr. Holmes-Farley's article, the calculator assumes that the mass of
magnesium consumed by biological processes is equal to 6.5% of the mass of calcium consumed.
Note that, ignoring trace impurities in the ingredients, Dr. Holmes-Farley's recipies only dose chloride, sodium,
sulfate, magnesium, calcium, alkalinity, and potassium. Each of these ions, with the exceptions of calcium and
alkalinity, can be selected for calculation. The calcium and alkalinity levels are assumed to remain constant
(see above) and have therefore been excluded. The "Non-Dosed Ion" option can be used to estimate the change in
concentration of any other ion (Bromide, Strontium, Fluoride, etc.).
