Mix two strengths or dilute to a target concentration.
This calculator has two modes. The mixing mode combines two solutions with different strengths and estimates the final concentration. The dilution mode calculates how much water or another 0% solution must be added to lower a starting concentration to a target level.
Use the same volume unit for every entry. Gallons, liters, quarts, or ounces all work as long as the units remain consistent.
The math compares concentration and volume. Mixing gallons with quarts or liters without converting them first will produce the wrong result. Keep every volume entry in one unit from start to finish.
The math works for concentration and volume, but chemical compatibility and safe handling must come from the product label. Never combine products just because the math works.
Only when they are compatible forms of the same product and the labels allow it. Never mix different chlorine types together.
Adding water or a 0% solution can only reduce concentration. It cannot make the solution stronger.
No. It assumes simple mixing with no reaction, heat release, density change, or volume contraction.
This tool handles the math, not the chemistry. If the product labels do not clearly allow the mixture, do not combine them.
