## What is Clear Tank?

Keep a clearer record of life in your aquarium.

Clear Tank brings water tests, photos and care tasks together in a journal for each tank, helping you look back at changes and plan everyday maintenance.

A NOTEBOOK FOR EVERY TANK
Create separate profiles for freshwater, planted, marine and brackish aquariums. Record actual water volume and established dates, and organize livestock, plants and equipment.

WATER TESTS AND TRENDS
Log temperature, pH, total ammonia, nitrite, nitrate, GH, KH and salinity. Leave untested values blank, review individual metrics over time and set personal target ranges.

A PHOTO JOURNAL OF CHANGE
Add camera or library photos, with up to five images per photo entry plus optional captions and notes. Browse a visual timeline that also includes photos attached to water tests and maintenance records.

CARE TASKS AND REMINDERS
Record water changes, cleaning and other maintenance. Create one-time or repeating tasks and enable local notifications. Completing a repeating task schedules its next occurrence from the completion date and your chosen interval.

PRACTICAL AQUARIUM TOOLS
Estimate water volume for several tank shapes and approximate freshwater weight. Calculate theoretical water-change proportions, scale product-label doses and convert volume, temperature and hardness units.

REPORTS, COMPARISON AND BACKUPS
Create PDF reports for a tank and date range. Compare readings across tanks while switching metrics and time ranges. Export original water-test values as CSV, or create a full ZIP backup containing records and attached photos to restore later.

Choose light, dark or system appearance. Available in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, Brazilian Portuguese and German.

BEFORE YOU START
- No account is required. Aquarium records and photos stay on your device; the app does not provide its own cloud sync.
- An internet connection is required at each cold start to retrieve app configuration.
- When ads are enabled, Today and Tanks may show banners. If no unused reward is available, one completed rewarded ad unlocks one PDF or one comparison session. When ads are disabled, these features are available directly.
- Restoring a backup replaces current records. Exported backups are not encrypted by the app; keep them safe.
- Clear Tank is a personal journal and calculator, not veterinary advice. Check test-kit units and product instructions. Calculations do not provide a diagnosis or guarantee aquarium health.
