PoolBox™ Index

A single index
to understand how the water has behaved.

The PoolBox™ Index summarises water behaviour on a scale of 0 to 10. The main index covers the last 7 days and considers time spent within the pH and redox ranges, together with filtration recommended according to water temperature.

What it is

A clear, objective indicator.

The PoolBox™ Index is a reference from 0 to 10 for water behaviour over a period.

The main period is the last 7 days. The 3, 14 and 30-day windows help show how the water changes over time.

What the index takes into account

Three variables.
One clear reference.

The index is based on pH, redox and filtration completed compared with the recommendation based on water temperature.

H₂O01

pH

Tiempo dentro del rango de referencia.

ORP02

Redox

Tiempo dentro del rango de referencia.

h03

Filtración

Horas realizadas frente a las recomendadas según la temperatura del agua.

How it is generated

From period data
to a clear reference.

The main index is calculated over the last 7 days.

  1. 1

    Collects measurements

    from the period analysed.

  2. 2

    Evaluates pH and redox

    based on time spent within their reference ranges.

  3. 3

    Compares filtration

    with the recommended time based on temperature.

  4. 4

    Produces a result

    de 0 a 10.

Index scale

From 0 to 10,
easy to interpret.

These ranges describe water behaviour during the period.

8–10Very good and consistent water behaviour.
6–7.9Adequate behaviour, with some occasional deviations.
< 6Could be improved. Review pH, redox and filtration trends.

How to read the index

A single reading
does not tell the whole story.

The 8.6/10 score is an illustrative summary of water behaviour over the last 7 days. The figures are examples, not live data.

The result considers time spent within the pH and redox ranges, together with filtration recommended according to water temperature.

The whole picture

The same spot pH can show a different trend.

Trend over time

The main index.
Last 7 days.

The 7-day period provides a steadier reference that is less sensitive to isolated fluctuations. You can also compare 3, 14 and 30 days to observe trends.

What it is for

A reference to track the water.

01

Understand

Summarises the monitored variables in one clear reading.

02

Compare

It lets you compare a pool at different times.

03

Detect

It makes changes easier to spot.

04

Explain

Makes it easier to communicate water behaviour with a simple reference.

Transparency

The index does not replace the underlying data.

The score summarises time spent within the pH and redox ranges and filtration compared with the recommendation based on water temperature.

Frequently asked questions

Questions about the PoolBox™ Index.

Clear answers to help you understand the score and what it means.

What period is used to calculate the index?+

The main PoolBox™ Index is calculated over the last 7 days. The 3, 14 and 30-day periods can also be viewed to observe trends.

Which variables does it consider?+

It evaluates how long pH and redox stay within their reference ranges and compares filtration completed with the recommendation based on water temperature.

Is temperature a fourth indicator?+

No. Temperature is used to set the recommended filtration time; it is not scored as an additional factor.

Does the index replace water analysis?+

No. It is a monitoring reference based on measured variables and does not replace water analyses or any required sanitary checks.
