Does this calculate every pool chemical?
No. Only the named models on the linked pages are supported. A model that does not match your product should not be used as a substitute.
Pool Chemical Calculator
Choose a calculation by the measurement and product you actually have. Water volume, product identity and the correct target come before a quantity estimate. Supply budgets are a separate task.

Choose the matching calculation
A chemical budget estimates dollars over time; a quantity tool answers a narrower mass-balance or label-table question. Neither diagnoses water or approves treatment.
| Task | Required information | Boundary |
|---|---|---|
| Salt quantity | Water volume, measured salinity, chlorinator target, bag mass | Dry NaCl equivalent; no target preset |
| ProSide chlorine mass | Volume, free-chlorine readings, matching resealable package | Theoretical available-chlorine balance, not liquid volume |
| ProSide shock range | Volume, matching resealable package, confirmed label scope | Label endpoints, not a selected dose or target |
| Alkalinity First quantity | Water volume, total alkalinity as CaCO3, target, matching label | One sodium bicarbonate product table |
| HTH stabilizer quantity | Water volume, CYA reading, target, matching 98.5% product table | Not a universal CYA product formula |
| Chemical budget | Pool type and size | USD/month supplies; no dose |
Keep a usable water record
Record the date, pool water volume, test method, current readings, exact product name and units before comparing estimates. An unexplained low or high reading should be verified rather than converted immediately into another purchase. Do not use wall height as water depth or substitute Imperial gallons for US gallons. The linked tools preserve units when switching displays.
Chlorine and shock answer different planning questions
The chlorine tool uses one named granular product's available-chlorine fraction for a theoretical mass balance. The shock tool scales that product's pool-shock label range without selecting a dose or target. Neither supports single-use bags or liquid formulations, and their results must not be added together. A liquid product needs a verified concentration basis and density or label-volume model. No generic pH or universal shock treatment is provided.
Methodology and responsibility
Each linked quantity tool states whether it uses a mass-balance approximation or a specific manufacturer table. Targets are entered by the user and quantities are separate from purchase rounding. Pool Cost Planner is the publisher; these pages have not received independent professional review. Numerical checks do not certify water quality or safe swimming. Never use these estimates as mixing, handling or application instructions.

FAQ
Is a saltwater pool chemical-free?
No. Saltwater describes a chlorination system, not an exemption from disinfectant testing or other water-care requirements.
Can a correct calculation prove the pool is safe?
No. Actual readings, applicable guidance and equipment condition still determine the next step.
