Free Pool Calculators for Ellis County Pool Owners
Pool math shouldn't be a guessing game. These calculators give you a real number for your pool — gallons, chlorine, acid, shock, salt — and tell you when the math runs out and a real test kit takes over. Built by a Waxahachie pool service, not a chemical brand trying to sell you a bucket.
Pool chemistry calculators
Run the numbers before you dose
Start with gallons. Then dose for your pool, not the generic 10,000-gallon pool on the back of the bucket.
- pool gallon calculator
Pool Volume Calculator
Get a practical gallon estimate before you add chlorine, acid, salt, stabilizer, or any other chemical.
Run -> - how much chlorine to add to pool
Free Chlorine Dose Calculator
Calculate a practical free chlorine dose for North Texas pools without trusting the back of the bucket.
Run -> - pool shock calculator
Pool Shock Calculator
Shock based on your CYA level, not a one-bag-per-10,000-gallons label rule.
Run -> - muriatic acid pool calculator
Muriatic Acid Calculator
Lower pH with a conservative acid dose that accounts for pool gallons and alkalinity.
Run -> - baking soda for pool alkalinityComing soon
Baking Soda Alkalinity Calculator
Raise total alkalinity with sodium bicarbonate so pH stops bouncing around.
Coming soon - pool stabilizer calculator
Cyanuric Acid Stabilizer Calculator
Add CYA carefully so chlorine survives the sun without getting buffered into weakness.
Run -> - pool calcium hardness calculatorComing soon
Calcium Hardness Calculator
Protect plaster and equipment by keeping calcium hardness in a practical range.
Coming soon - pool salt calculator
Pool Salt Calculator
Estimate pounds and 40-lb bags of pool salt needed for your salt system target.
Run -> - balance my poolComing soon

Quick Reference
Pool Chemistry Target Ranges
The ranges each calculator above dials toward — pulled straight from the same FAQs and testing guidance on each tool.
| Chemistry Parameter | Target Range | Test Kit Needed |
|---|---|---|
| Free Chlorine (FC) | 2–4 ppm | DPD or FAS-DPD kit |
| Shock Target FC | Depends on CYA — use calculator | FAS-DPD + CYA turbidity test |
| pH | 7.4–7.6 | pH test kit + alkalinity reading |
| Total Alkalinity (TA) | 80–120 ppm (60–80 for salt pools) | Total alkalinity titration test |
| Cyanuric Acid (CYA) | 30–50 ppm (60–80 ppm for salt pools) | CYA turbidity test |
| Calcium Hardness (CH) | 200–400 ppm (150–250 for vinyl/fiberglass) | Calcium hardness drop test |
| Salt | ~2,700–3,500 ppm (check your generator's manual) | Digital salt meter or salt test strip |
| Full Panel | Multi-parameter — use calculator | Complete drop kit (FC, pH, TA, CYA, CH, salt) |

Leak and freeze tools are coming
Two more tools are in the build pipeline — a bucket-test diagnostic for when your pool is losing water, and a freeze-prep checklist for the week before a hard North Texas cold snap. Both come straight from the calls we get most.

A practical check for deciding whether the pool is losing water to evaporation or a real leak.

Built for real pools, not perfect lab conditions
A&M is a Waxahachie pool company that's been on Ellis County pools for 20 years. These calculators are honest about real-world variance — gallons are estimates, chemicals lose strength sitting on a hot garage shelf, and a Texas thunderstorm changes the water in an afternoon. Use them to skip the guesswork. But when the water keeps fighting back, a real test kit and an on-site look beat any calculator on the internet — including this one.
