SunnyReef

Full control of your reef: water tests, charts, ICP reports, dosing with a dose advisor, and an AI assistant — on iPhone, iPad and Mac, synced through iCloud.

SunnyReef is a marine aquarium journal for iPhone, iPad and Mac. Log water tests, watch trends on charts, import ICP lab reports, plan your dosing and ask an AI assistant about your reef — all in one place, synced through iCloud.

TESTS & PARAMETERS • 12 parameters: KH, calcium (Ca), magnesium (Mg), nitrate (NO₃), phosphate (PO₄), pH, salinity, temperature, plus trace elements: potassium (K), strontium (Sr), iodine and iron (Fe) • A clear status for every parameter against its target range — with custom ranges for your own tank • Historical charts and statistics: parameter trends over time

ICP REPORTS • Import lab results from: Aquaforest Lab, ATI ICP, Triton, Fauna Marin, Oceamo • Values are read from the report automatically by an AI agent and compared with your previous tests (requires an AI key — see below)

BRING YOUR HISTORY • CSV import from Excel, Numbers or Google Sheets — carry your existing measurement history with you

DOSING • A new Dosing tab: set each supplement schedule once — a periodic table of elements shows every item at a glance • Bottle supply warnings 7 and 3 days ahead • Estimated level on the Dashboard, History chart and Dosing table — measured values and their statuses never change • A dose advisor computes real consumption from your tests and ICP and suggests a safe dose — always a suggestion, never auto-dosing • Label converter (ml/drops, L/gal, mg/µg per litre, dKH) and a salt batch profile

LIVESTOCK & FEEDING • Track your fish, corals and invertebrates — species, purchase batches with prices and dates • Loss history with cause and note — undo an accidental loss and the animal returns to your living stock • Group feeding: one food, frequency and notes for a whole category; any species can have its own plan • The AI assistant knows your livestock — ask about stocking compatibility or have it set the feeding plan

GALLERY, CALENDAR, REMINDERS • Reef photos with water parameters from the nearest test saved in the background • Calendar with daily notes • Reminders with notifications — water changes, tests, top-offs

MULTIPLE AQUARIUMS • Separate tank profiles, including saved lighting settings

SYNC & BACKUPS • iCloud sync between iPhone, iPad and Mac • Automatic backup to a folder of your choice (e.g. iCloud Drive), plus manual export and restore of a .sunnyreef file

AI ASSISTANT — WITH YOUR OWN KEY SunnyReef connects to AI models using your own API key: • Claude (Anthropic) — paid key, highest quality analysis, understands photos • Gemini (Google) — free key, fully functional agent with photo analysis The assistant knows your results, answers questions about your parameters, analyzes coral photos and saves notes on your request. AI answers are informational and do not replace the knowledge and judgment of an experienced reef keeper.
