Pool Water Calculator

About Pool Water Calculator Android App

Pool Water Calculator provides everything you need to quickly balance and maintain your pool or hot tub. Built for both beginners and experts alike, Pool Water Calculator provides treatment directions and dosage information for a wide variety of pool chemicals and water quality parameters for nearly all pool types and spas.

Visualize your water quality history through an assortment of beautiful and reactive graphs, enabling you to follow your progress or identify potential problems. Track your chemical additions and maintenance events, or update previous datapoints as needed to fine-tune your records.

Manage up to five different pools or spa profiles, with each profile maintaining a unique water chemistry and treatment history, individual chemical targets, custom notes, and maintenance records.

Quickly find the optimal chemical targets and ranges based on your pool type and current water chemistry. Customized water quality graphs illustrate your pool's chemistry in relation to the ideal targets or applicable water chemistry curves, while guidance items will advise you if you're in range or need to take action before problems occur.

Customize chemical strengths (1 to 100%) to find precise dosing information for nearly any standard pool chemical.

The Dosing Guide explains each water quality parameter and its role in balancing your pool, the treatment chemicals available for adjusting each of these parameters, and instructions on how to add them to your pool or spa.
