The build

Step 01

Collect samples

Gather tap, rain, pond water, etc.

Step 02

Test pH

Use indicator strips on each.

Step 03

Check clarity

Compare how far down you can see.

Step 04

Record

Log and compare all readings.

Working Principle

Each test probes a different property — acidity, clarity, temperature — and together they sketch a basic health profile of the water.

The science behind it

A closer look

Water quality is multi-dimensional; combining cheap tests reveals differences between natural and treated sources.
