The irritation
My mixed reef generates water tests, livestock changes, equipment notes, and recurring chores. A spreadsheet held the facts but did not make the health of the tank easy to read.

Built because…
The real build story.
What I built
I built a dashboard around the real Fish Haus log: nine water parameters with ideal ranges and trends, a reef-health score and radar chart, testing history, recurring maintenance, livestock notes, and a dated journal backed by Google Sheets and Apps Script.
The hard part
Each parameter has different units and rhythms, while a living tank never reduces cleanly to one score. The interface has to surface drift and overdue work without claiming biological certainty.
Under the casing
Proof, not decoration.

Outcome and lesson.
Where it landed
Fish Haus is the working personal operations dashboard for my Fluval EVO 13.5-gallon mixed reef, using live sheet data rather than a generic aquarium demo.
What stayed
Personal software works best when it matches the ritual around the thing: test the water, log the change, complete the maintenance, and know what deserves attention next.
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.
