About this app
SereneSea is your ultimate reef-keeping companion, designed specifically for saltwater, coral, and reef aquarium enthusiasts.
Whether you are a beginner taking your first steps in the hobby or an advanced reefer managing SPS, LPS, water chemistry, and automated dosing schedules, SereneSea helps you centralize all your tank data, maintenance schedules, livestock logs, and water parameters in one organized system.
【Key Features】
📊 Water Parameter Tracking & Trend Charts
Log essential water parameters such as KH, NO3, PO4, Ca, Mg, pH, salinity/specific gravity, and temperature. Monitor long-term aquarium stability with clean, intuitive trend graphs.
🐠 Multi-Tank Management
Create and manage profiles for multiple reef tanks. Keep track of basic setup details, photos, water volume, livestock, equipment, logs, and maintenance tasks for each tank.
📸 Livestock Database & Growth Diary
Create dedicated profiles for your fish, corals, and invertebrates. Log photos, health status, and growth milestones. Track their journey over time—from a newly introduced frag to a colony in full colony.
🗓️ Maintenance Schedules & Reminders
Schedule water changes, skimmer cup cleaning, filter media rinsing, equipment maintenance, dosing of trace elements, and more. Never miss a task with timely push reminders.
📝 Daily Logs & Chronological Timeline
Log feedings, water changes, dosing adjustments, equipment replacements, livestock behavior, or any other reef events. Everything is organized in a clear, easy-to-read chronological timeline.
🔧 Equipment & Supply Inventory
Organize your lighting, protein skimmers, wavemakers, dosing pumps, and other equipment. You can also keep track of your stock of aquarium salt, filter media, test kits, and additives.
🧪 Practical Reef Calculators
Access built-in calculators for net water volume, water change percentages, salt amount, KH/Ca/Mg adjustments, and dosing schedules, eliminating tedious mental math.
⏱️ Test Timer & Lab Stopwatch
Use the built-in timers and alarms for waiting on water test kit reactions, dosing, or quick maintenance tasks to keep your workflow precise and stress-free.
💾 Backup & Restore
Securely back up your data and restore it whenever needed to protect your valuable reef history, livestock profiles, photos, and logs.
