Why StableTank

A focused aquarium journal with tools that help you act sooner.

It is designed for hobbyists who want one place for daily logs and the kind of decision support that usually lives in spreadsheets, guesswork, and memory.

Water chemistry that stays readable
Log pH, ammonia, nitrite, nitrate, GH, KH, and phosphate with a dashboard built for fast tank check-ins.
Maintenance and equipment in one place
Track water changes, filter service, feeding cadence, and lighting without juggling spreadsheets or notes apps.
Planted tank insight, not just recordkeeping
See stocking pressure, nitrate forecasts, algae diagnostics, and stability signals before issues get expensive.
Cloud-backed access when you need it
Sign in to keep your aquarium journal, maintenance history, and ecosystem context available across sessions.
How it works

From tank setup to long-term stability.

01
Create your aquarium profile
Start with tank size, filter, lighting, and feeding cadence so your journal has real context from day one.
02
Log chemistry and maintenance as you go
Capture quick readings, water changes, journal notes, and filter work without slowing down your routine.
03
Use the dashboard to guide decisions
Turn those logs into nitrate forecasts, stocking cues, and algae troubleshooting that helps prevent problems.

Spend less time reconstructing what happened in your tank.

Keep chemistry, maintenance, stocking, and planted-tank decisions connected in one dashboard so your aquarium journal is actually useful when something starts drifting.
