Write a baseline you can trust
Give the aquarium a recognizable name. Add freshwater or saltwater, measured dimensions and known equipment models. If you record capacity, say whether it comes from the tank label or your own estimate; substrate and decorations mean nominal capacity is not the same as actual water volume.
Inventory livestock without false precision
List each known species, the count you can confirm and any uncertain identification. Do the same for plants or corals. A single wide photo may miss a hiding fish or confuse similar plants, so review a generated list before using it as your record. “At least six visible” is more honest than a confident count you cannot verify.
Separate description from interpretation
“Water looks cloudy in today’s photo” is an observation. “The biological filter has failed” is an interpretation that needs more evidence. Record what you saw, when you saw it and what you measured. This makes your notes easier to explain to someone helping with the aquarium.
Keep a change note you can reuse
For each change, write: Date / What changed / Why / What I observed afterward. Examples include moving a plant, replacing a lamp or adding livestock. Put measured water results in separate dated entries with units. That structure helps you ask better follow-up questions without implying that two events prove cause and effect.
Know what your app actually saves
Aqua AI’s current preview creates an editable aquarium profile and saves it on the device. Review the scan, correct the entries and keep your own backup of important details. The development app also supports linked water-test history and metadata sync. Photos remain on the device, and cross-device restoration is not available. These are development features, not a publicly released service.
About these field notes
These guides are written for aquarium keepers by the Aqua AI project with AI-assisted drafting. Product descriptions are checked against the development implementation. Practical checklists are editorial suggestions; they are not controlled experiments or veterinary review. Water-chemistry claims link to manufacturer guidance. Follow the instructions supplied with your exact test kit.
