Actual Tankquil trend view.
TESTING & TRENDS
See the pattern behind every reading.
Tankquil brings your recorded results, target range, and recent highs and lows into one clear view. Compare different time periods, recognize changes, and know when a follow-up test may be worthwhile.
Flexible history
Review 7 days, 30 days, 3 months, or 1 year.
Target-range context
See readings alongside the range you’re aiming for.
At-a-glance summaries
Compare low, average, and high results.
From test result to daily routine.
MAINTENANCE & DOSING
Tankquil connects product-aware calculators, aquarium volume, recorded results, and measured consumption to help estimate correction and maintenance doses. Then organize the schedule, review what was planned, report delivery issues, and estimate when supplies may run low.
Calculate with context
Use tank or effective water volume, current and target results, the selected product, and measured daily consumption to estimate correction and maintenance amounts.
Track the dosing routine
Review completed and upcoming doses, split daily amounts across a schedule, and report missed, partial, interrupted, or different automated deliveries.
Plan the next refill
Estimate remaining reservoir supply, low-supply timing, runout, pump runtime, and refill history from the schedule and delivery issues you report.
Tankquil records and estimates dosing activity. It does not control, communicate with, or verify a physical doser. Always confirm test results and follow the product’s instructions.
SPECIALIZED DOSING WORKFLOWS
More than a
one-size-fits-all calculator.
Tankquil includes product-aware workflows for complete systems, coordinated multi-part schedules, nutrient management, and staged media treatments. Each workflow keeps the relevant calculations, testing, timing, and safety precautions together.
Tankquil supports planning and recordkeeping. Always verify test results and follow the selected product’s instructions.
Complete systems
Build an All-For-Reef plan from aquarium volume and a starting or established routine, with gradual weekly adjustments and regular testing.
Coordinated dosing
Calculate paired alkalinity and calcium demand, compare conflicting estimates, and stagger multi-part schedules to keep supplements safely separated.
Staged nutrient reduction
Start RowaPhos conservatively, record the installed amount, and schedule the first retest 24 hours later before deciding whether to replace the media.
AQUARIUM 101
Guidance from setup through year one.
Choose a learning path for your aquarium and follow 17 guided lessons from setup and cycling through routine care and the first year. Quil explains why each step matters while Tankquil keeps your progress connected to the aquarium you’re caring for.
Three learning paths
Choose Fish Only, FOWLR, or Reef guidance.
Evidence-led cycling
Evaluate your logged results—not a generic countdown.
Help when you need it
Use dashboard coaching, cycling evidence, and a plain-language parameter glossary.
PRIVATE STABILITY PLAN
Know what deserves attention first.
Tankquil reviews your recent readings, trends, testing history, dosing, and maintenance to create a focused plan for your aquarium. The most useful next steps are placed in a clear order so you can act without feeling overwhelmed.
Three focused priorities
See the most useful next steps in the order they deserve attention.
Evidence behind the guidance
Understand which readings, trends, and care history contributed to each suggestion.
Private and under your control
Your Stability Plan is created from aquarium information stored on your device. Review, snooze, or resolve each step when you are ready.
YOUR DATA
Your aquarium history. Ready when you are.
Create a structured export for analysis with a tool you choose, preview exactly what it contains, or protect your records with backup, restore, and CSV tools. Tankquil does not upload the analysis file—you decide where to save or share it.

Tankquil prepares information for use with a separate analysis tool; it does not provide an integrated AI service or automatically transmit aquarium data. Review imported or restored information before relying on it.
Choose what to include
Select a time range and prepare aquarium details, target ranges, test results and methods, dosing, maintenance, livestock, equipment, and recent events.
Share on your terms
Preview the structured file before exporting it. Receipts, prices, personal contacts, and photos are excluded, and Tankquil does not upload the file.
Back up and import
Export or restore a backup on the same platform, import existing test readings from CSV, or save Tankquil’s CSV template.
Leave the tank. Not the guesswork.

Only approved tasks
Choose the tests and maintenance your sitter may perform, or begin with your current maintenance tasks.
Create a focused care plan for someone watching your aquarium. Set the trip dates, feeding instructions, approved tasks, emergency guidance, equipment notes, and anything that must not be changed.
Tank Sitter Mode shows only the care instructions and checklist. Checklist progress is saved on the device being used.
TANK SITTER
Clear guardrails
Record feeding instructions, an emergency contact, equipment information, and explicit directions about what must not be changed.
A simpler handoff
Open a focused Tank Sitter checklist or share and print the care instructions before leaving.
Testing that remembers how you tested.
TESTING WITH CONTEXT
A number rarely tells the whole story. Tankquil guides each testing session, keeps the method connected to the result, and preserves the conditions surrounding the reading so later trends and follow-up decisions have the context they need.

Guided sessions
See which parameters are due, include optional tests, and work through a consistent testing session.
Results with their method
Record an exact or qualified result while keeping the selected test method or digital checker attached.
Conditions that stay attached
Preserve confirmations, water changes, dosing, lighting conditions, and sample location with the reading.
Research before you add livestock.
SPECIES RESEARCH & PLANNING
Tankquil brings species research, tank-fit checks, and compatibility guidance into one planning flow. Explore prospective livestock, understand what each species needs, and see when a pairing deserves caution before it reaches your aquarium.
Explore the species guide
Search by common or scientific name, browse categories, apply filters, save favorites, and compare prospective livestock.
Understand each species
Review temperament, adult size, minimum tank size, water requirements, reef safety, care notes, and other planning details.
Check combatibility first
Compare prospective tankmates, see when a pairing deserves caution, and understand the factors behind the result.
