SereneSea - Reef Tank Journal

Centralized water, maintenance, livestock & equipment logs. New AI Import: structure old data with your preferred AI, preview in app, and import with confidence.

When keeping a marine tank, data is rarely missing—it's usually scattered across test logs, note apps, photo galleries, and various tools.

SereneSea centralizes water parameters, maintenance routines, livestock, equipment, photos, and key changes into a single tank profile. It helps you not only log today's details but also look back and truly understand your aquarium's journey.

【Water Parameters & Long-Term Trends】 Track essential marine metrics like Ca, Mg, KH, NO3, PO4, salinity, and specific gravity, or add your own custom parameter items. Use trend charts to review long-term changes over time, cross-referenced with dosing and lighting adjustment logs to clearly see the impact before and after every tweak.

【AI Import for Historical Water Logs】 No need to manually re-type old water parameter records stored in notes, spreadsheets, screenshots, or other places. SereneSea provides a structured prompt/format—simply use your preferred AI tool to organize your raw data and paste the result back into the app. Preview, edit, and select which entries to keep before importing. Nothing is written to your official records until you confirm.

【Maintenance & Reminders】 Set up schedules for water changes, cleaning, additives, and equipment maintenance, and track both pending tasks and completed history. Every completed task leaves a historical record, so daily care no longer relies solely on memory.

【Livestock, Equipment & Consumables】 Centralize records for fish, corals, hardware, and media, including name, category, date, price, notes, and more. Includes AI Import for livestock and equipment—batch-organize your old records and verify each entry in the app before importing.

【Photos, Milestones & Tank History】 Keep tank photos and major events together on a unified timeline—including livestock additions, hardware upgrades, parameter adjustments, and tank status changes. Over time, SereneSea becomes more than just a logging tool; it becomes the growth history of your reef tank.

【Shared Tank Maintenance】 If your aquarium is cared for by more than one person, use the Shared Maintenance feature. Co-maintainers can view shared tank data, complete scheduled tasks, and add water records or milestone events, reducing repetitive actions and communication gaps.

【Backup & Restore】 Supports ZIP file export/import as well as optional Google Drive cloud backup. Years of accumulated tank records don't have to stay trapped on a single device.

【Practical Tools for Marine Aquarists】 Includes built-in calculators and helper tools for marine tanks, keeping testing, maintenance, and daily management all in one app.

【Built for Marine Hobbyists】 Find local marine aquarium shops in Taiwan, making it convenient for both tank management and real-world store visits and purchases.

Core features can be used immediately without account registration. Simply choose to sign in with Google Drive when you need cloud backups or shared maintenance. Primary tank care features are free to use; VIP is available mainly for an ad-free experience and to support ongoing development.

Record every change in your reef tank with care.
