How it works
Each parameter is scored against the recommended range for your selected tank type. The tool returns a status (OK / watch / urgent fix), the specific issue, and the recommended action with links to relevant guides.
This is reference guidance, not a replacement for your judgment. If multiple parameters are red, the safe move is a 30% water change and a re-test in 4 hours.
