Turn a test-kit dose into your pool’s dose
If your kit recommends 12 fl oz for 10,000 gallons, a 25,000-gallon pool needs 30 fl oz of the same product. Enter your kit’s numbers above and the calculator does the scaling.
Use an acid-demand test to lower pH, or a base-demand test to raise it. These are the extra drops in a compatible test kit that measure how much adjustment your water needs. After counting the drops, look up the dose in the kit’s treatment chart.
Where do I find the recommended dose?
Look in the instructions or guidebook supplied with your test kit. Taylor’s #5165 instructions direct users to Guidebook #2004B for treatment amounts after the acid or base demand test.
Choose the chart row for your drop count and product strength. Enter its dose and the pool size it applies to. Keep liquid fl oz separate from oz by weight.
Why pH alone does not give an acid dose
Two pools at pH 8.0 can need different amounts of acid because their alkalinity and buffering differ. A demand test measures that difference. Once you have its recommended dose, pool volume gives the amount to add.
Follow the chart’s maximum amount per treatment, circulate and retest pH before another addition.
Add, circulate, then retest
Follow the product label for application and mixing time, then retest before adding more. Keep chemicals separate: never mix chlorine with acid or other chemicals.
Common questions
How do I lower pool pH from 8.0 to 7.4?
Use your kit’s acid-demand test to reach the 7.4 color, then find the dose in its treatment chart. Enter that dose and your pool volume here. The amount depends on your water’s buffering as well as its pH.
Can I calculate a dose from a test strip?
A strip gives a pH reading, but not the amount of acid or base needed. Use a kit with a demand test or get a treatment dose for your water from a pool-water test service.
Can I use this for pH increaser?
Yes. Choose Raise pH and enter the matched base-demand chart dose for your product. Use the chart’s weight unit if it specifies a dry powder.
