Pool Water Calculator is an all-in-one pool and spa management suite containing the tools and features you need to quickly balance and maintain your pool or spa.

Use the chemistry calculator to quickly find the chemical dosages needed to balance your water. Customize your preferred chemical strengths (1 to 100%) to find precise dosing information for nearly any standard pool chemical.

Save and track your water parameters, chemical additions, and pool maintenance events, or update previous datapoints to fine-tune your water testing records. Create customized chemicals and maintenance items, and share or export your water history.

Visualize your water history through an assortment of beautiful and reactive graphs, enabling you to follow your progress or identify potential problems.

Tailor your water profile and liner type to quickly find the best target recommendations. Customized quality graphs illustrate your pool or jacuzzi's water 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.

Backup or recover your water profile, history, and settings using iCloud. Find your pool volume using the volume calculator.

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

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