Ready when you are
Add your fish and click “Check my tank.”
Do not chase the score by changing water chemistry suddenly.
This score is only a screening tool. Do not make large or immediate changes to pH, GH, KH, TDS, temperature, or other water parameters just to raise the score. Rapid changes can stress or injure fish, shrimp, and snails. Make changes gradually and based on the needs of the animals in the tank. If ammonia or nitrite is present, treat that as a water-quality problem rather than a score problem.
