Aquarium log
Track My Jellies logs the water in your tank, charts every parameter against the range jellyfish actually tolerate, and shows you the moment something starts to drift.
Salinity, 30 - 35 ppt safe band, with a water change marked
What it tracks

And the animals themselves
Count
any drop flagged
Bell diameter
drop over 15% in 14 days
Pulse rate

Every parameter plots over time with its safe band shaded behind it, so a slow drift is obvious long before it becomes a problem.
Record what you swapped out and see it as a percentage of your tank, marked on the chart next to the readings around it.
Export your whole log as Markdown that opens by telling the model it is an "experienced saltwater aquarium advisor with specific knowledge of jellyfish systems" — then paste it into any chat.
The safe ranges, the parameters, and the export prompt are all written for jellyfish rather than borrowed from a reef tank.
