Please note: the Visual Water Check is a colour-based estimate only — it can't detect dissolved ammonia, nitrite or pH, and is no substitute for a test kit. AquariumMate doesn't offer veterinary or medical advice; always research your species and consult an expert if unsure.

Some optional extras (full trend history, breeding notes and CSV export) can be unlocked by watching a short ad.

Happy fishkeeping! 🐡
