TankLog vs Reef Analysis

Built by an aquascaper, for aquascapers. TankLog is a free freshwater aquarium journal for planted tank and shrimp hobbyists. No login. No subscription. Completely offline — your data stays on your device, nothing ever sent to a server. Built for the people who track CO₂ levels, obsess over KH and GH for their neocaridina colony, and want to know when their nitrates started creeping up — not a generic fish app trying to cover everything. WATER TESTING & PARAMETER TRENDS Log pH, ammonia, nitrite, nitrate, KH, GH, phosphate (PO₄), TDS, and temperature. Every reading is graded instantly against your custom target ranges. Parameter Trends charts every test over time, making it easy to spot slow pH drifts, creeping nitrates, or KH swings before they affect your plants or livestock. Each parameter page shows your previous reading alongside recommended ranges. CO₂ ESTIMATION TankLog calculates dissolved CO₂ from your pH and KH readings and displays the result as a color-coded zone — very low, low, ideal, high, or at risk. Essential for high-tech planted tanks where CO₂ directly drives plant growth. CARE SCHEDULES & ACTIVITY CALENDAR Build a maintenance schedule for water tests, water changes, filter cleans, fertilizer dosing, feeding, and more. TankLog sends push notifications when tasks are due and flags overdue items on your home dashboard. The Activity Calendar shows your full care history and upcoming due dates in one view — tap any overdue item to jump straight to the log form. DOSING & FERTILIZER TRACKING Log every fertilizer, mineral supplement, and treatment — with product, amount, and date. Set dosing schedules and track exactly what went into your tank and when. WATER CHANGES, FEEDING & CLEANING Log water changes with volume and percentage. Log feedings with species tags and multiple schedules. Log cleaning tasks — filter maintenance, substrate work, glass cleaning — each with its own schedule and history. ACHIEVEMENTS Earn badges for consistent water testing, on-time care schedules, and overall water quality grades. Tap any badge to see how you earned it, when your streak started, and how to keep it going. EQUIPMENT & LIVESTOCK Record every piece of equipment — lighting, filtration, CO₂ system, heater, pumps. Log fish, invertebrates, and plants with dates added and notes. MULTIPLE TANKS Manage up to 3 tanks, each with its own independent parameters, schedules, livestock records, and history. Switch between them with one tap. YOUR DATA, YOUR WAY Export your complete tank history as JSON anytime. Import it back on the same device or a new one. No cloud dependency. No account to lose access to. Your data is yours, always. No AI gimmick. No subscription. No paywall. Just a well-built, honest tool from someone who loves this hobby as much as you do. Free forever. Metric and imperial units · 12h and 24h time · Light and dark mode · iPhone and iPad

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.
