Aqua AIKnow which question your kit answers
Ammonia and nitrite are harmful to fish. Biological filtration converts ammonia to nitrite, then nitrate. pH describes acidity or alkalinity; it is not a substitute for an ammonia test. Check the analytes listed on your kit instead of assuming every multi-test strip covers everything.
Follow the instructions for this exact kit
Use the manufacturer’s sampling, mixing and reading procedure. Note the product name and read the result at its specified time. If you photograph a color comparison, include the matching chart and avoid filters. Lighting and camera processing can change how the colors appear.
Make the result understandable tomorrow
Record the aquarium name, date, time, parameter, value and unit. Include the kit and anything that happened recently, such as a water change or new livestock. If a color sits between two chart values, record that uncertainty rather than inventing a precise number.
Use a compact entry
Copy this structure into your own notes: Tank / Date and time / Test kit / Parameter and unit / Result or range / Recent change / Follow-up. Keep separate entries for separate parameters. A photo without a kit name, timing or units is much harder to interpret later.
Respond to evidence, not the prettiest number
Aqueon recommends ammonia and nitrite readings of zero in freshwater aquariums. Appropriate conditions depend on the livestock and context. If a result is unexpected, check the procedure and seek informed advice; if fish are distressed, obtain prompt help rather than waiting for an app result. Aqua AI does not currently provide production water readings or treatment instructions.
A result that keeps its meaning
| Record | Example format | Why it matters |
|---|---|---|
| Aquarium and time | Living-room tank · date and time | Keeps results from different tanks separate. |
| Kit and parameter | Exact kit name · nitrate (NO₃) | Distinguishes the kit and the substance measured. |
| Result and unit | Between two labeled chart values · mg/L | Preserves uncertainty instead of inventing precision. |
| Procedure and context | Reading time from instructions · recent water change | Makes a later comparison easier to interpret. |

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.
