The irritation
A reef tank produces a steady stream of measurements and observations, but scattered notes make it hard to see whether the whole system is becoming healthier or drifting.

Built because…
The real build story.
What I built
I built a dashboard for water parameters, livestock, journal entries, and a summarized tank-health view, with Google Sheets acting as an approachable operating record.
The hard part
Aquarium readings have different units, useful ranges, and rhythms. The interface has to reveal trends without turning uncertain biological signals into false precision.
Under the casing
Proof, not decoration.

Outcome and lesson.
Where it landed
Fish Haus is a working personal operations system that combines real reef-keeping data with a deliberately designed dashboard instead of another generic spreadsheet.
What stayed
The strongest personal software reflects the real ritual around it. A dashboard becomes useful when it helps decide what to inspect next, not merely when it displays more numbers.
This project has a physical address.
In the playable workshop, Fish Haus lives in the Systems & Maps Lab as a reef monitoring tank. You can inspect it without unlocking anything.
