AquaElectron: Aquarium Manager

AquaElectron is the all-in-one logbook for your aquarium — freshwater, planted or full reef. Track livestock, water parameters, maintenance tasks, expenses and your tank's whole story, with analytics that spot problems before you do.

EVERYTHING, TRACKED
• Aquariums — every tank in one place, with illustrated tank cards
• Livestock — fish, corals, invertebrates and plants, with growth logs over time
• Water parameters — log predefined or fully custom parameters, with trend charts and history back to day one
• Tasks & reminders — one-off and recurring maintenance, from water changes to daily feeding
• Expenses — categorized spending (food & supplements, equipment, livestock) with monthly trends, so you know what the hobby really costs
• Journal — a dated timeline of notes and photos per tank: milestones, rescapes and new arrivals in one scroll

CHARTS THAT DO THE WORRYING FOR YOU
• Anomaly detection — readings that deviate from your trend line are flagged instantly, so you catch a nitrate spike before your fish do
• Trend lines — regression over your history shows drift long before it's visible to the eye
• Forecasts — a projection shows where each parameter is headed next
• Full-screen analysis — tap expand and any chart rotates into a landscape workspace, with filters for date range, tags and type

1000+ SPECIES DATABASE
Adding livestock starts with a ranked instant search over more than a thousand fish, corals, invertebrates and plants — scientific names included. Start typing, tap, done.
