A balanced pool is a cheaper pool
Guessing is expensive. Getting it right the first time isn't.
Stop wasting chemicals
Add the exact amount your pool needs — not a splash-and-hope guess that burns through product.
Never rescue a green pool
A neglected pool can cost €100–300 in shock chemicals and a week out of the water. Catch the drift early.
Skip the pool service
Do it yourself in seconds and keep the €80–150 a visit — the app tells you exactly what to do.
