Reef Analysis

Reef Analysis — Complete Visibility for Your Reef Aquarium Your reef water data is scattered. ICP results sit in lab portals. Home test readings live in notebooks or spreadsheets. Live sensor data is buried inside each device's own app. Reef Analysis brings all of it into one place — the only app that unifies ICP lab results, home test logs, and live sensor data into a single, configurable dashboard. One tile per parameter. Every source. No more switching. Set your own target ranges for every parameter. Running high nutrients, low nutrients, or a full ULNS? Your dashboard reflects YOUR goals — not generic lab defaults. DASHBOARD One personalised view for every parameter — whether the latest reading came from an ICP test uploaded last week, a home test you logged this morning, or an Alkatronic reading from ten minutes ago. Reorder tiles, hide what you don't need, and switch between standard and gauge views. Multi-tank support with per-tank ranges. ICP TEST RESULTS Upload reports from every major lab — ReefZlements, ATI, Triton, Fauna Marin, Oceamo, Tropic Marin, Aquaforest and Modern Reef. Paste a barcode, drop a PDF, or enter a test ID and AI reads your report automatically. Bulk-upload your entire history in one go. Each element colour-coded against your custom ranges. Tap any parameter for a full trend chart across every test you've ever uploaded. Compare any two tests side-by-side and see exactly what changed. REEF MOONSHINERS ICP TOOLS The complete Reef Moonshiners R11a workflow built in. Load any ATI, Oceamo, Tropic Marin, or Modern Reef ICP result and get instant per-element assessment, daily dose calculations, and trace-element product guidance — no separate spreadsheet, no extra subscription. HOME TEST KITS Log alkalinity, calcium, magnesium, phosphate, nitrate, salinity, pH and more directly in the app. Values show up on your dashboard alongside ICP data so you can track shifts between lab tests. Built-in test-reaction timer with alarm so you never miss the read window. Prefer to automate? Push readings from Home Assistant, n8n, or any script via the REST API. LIVE MONITORING Connect your automated monitoring equipment for real-time readings: • Apex Fusion (Neptune Systems) • Alkatronic (Focustronic) • Mastertronic (Focustronic) • KH Guardian • KH Manager (Carer) • AquaWiz pH, alkalinity, calcium, magnesium, nitrate, phosphate and more — pulled in automatically and merged with your ICP + home test data. REEF LOG — YOUR TANK JOURNAL A timestamped journal for everything you do to your tank: water changes, dosing, equipment swaps, treatments, coral additions, maintenance, observations. Events overlay directly on your dashboard trend charts so you can correlate every parameter shift with what you actually did. HOME-SCREEN WIDGETS iOS and Android widgets show live tank readings on your home screen, lock screen, and (iOS) StandBy — check on your tank without unlocking your phone. WHAT IT DELIBERATELY DOESN'T DO Reef Analysis is a data platform, not a tank controller, livestock tracker, coral marketplace, task scheduler, or AI chat coach. Focused on one thing: complete visibility across every source of your reef water data.
