Aquaculture salt and alkalinity dosing calculator.
Estimate NaCl for a salinity increase and sodium bicarbonate equivalent for an alkalinity increase.
Aquaculture salt and alkalinity dosing inputs
Planning tool only. Monitor water quality and animal behaviour, validate species-specific limits and follow the direction of a qualified aquaculture professional before changing stocking, feed, aeration or water chemistry.
Method: One ppt rise needs one kilogram of salt per cubic metre. Bicarbonate uses the requested alkalinity rise as CaCO₃ equivalent with a 1.68 mass-equivalence factor.
Inputs used: Water volume = 20,000 L; Current salinity = 0.5 ppt; Target salinity = 2 ppt; Current alkalinity = 80 mg/L as CaCO₃; Target alkalinity = 120 mg/L as CaCO₃
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning tool only. Monitor water quality and animal behaviour, validate species-specific limits and follow the direction of a qualified aquaculture professional before changing stocking, feed, aeration or water chemistry. Rounding and excluded real-world terms can make an external result differ.
How this aquaculture salt and alkalinity dosing calculator works
One ppt rise needs one kilogram of salt per cubic metre. Bicarbonate uses the requested alkalinity rise as CaCO₃ equivalent with a 1.68 mass-equivalence factor.
A worked example
Raising 20,000 L by 1.5 ppt requires 30 kg of NaCl in this mass balance.
Can I add the full amount at once?
Do not assume so. Addition rate, water chemistry, species and system response matter. Measure water, dissolve and apply only under qualified local guidance.
Calculations run on your device. Review your results before exporting or sharing them.
Confirm the target and test before adding material
Salt is a direct mass balance: one ppt across one cubic metre is one kilogram. The alkalinity result is a chemical-equivalent screen, not an instruction to dose immediately.
Water source, species tolerance, pH, existing mineral balance and mixing method affect a safe response. Additions require a staged, measured farm protocol.
