What to check

Select the exact formulation and only the groups that share the water. Explicit Unknown and an omitted group are both unresolved; the tool keeps their provenance distinct.

Worked situation

A source may mention the biological filter and say nothing about snails. The map keeps one documented row and one unanswered row, even though both belong to the same system.

What to record next

Export the rows with their source links and checked dates. Take unresolved and conflicting entries to the manufacturer before relying on any conclusion.

The map organises saved evidence. It cannot match a bottle automatically, verify a tank, or approve a treatment. Your selections stay on this page and are included only if you download the map.
