The best water temperature is a function of the aquarium species. For instance, tropical fishes are better off in a temperature range of 24-28 degrees Celsius. Coldwater fishes, on the other hand, do well in temperatures below that.


The pH refers to the hydrogen power of the water. It indicates the alkalinity or acidity of water on a scale of 0 to 14. The ideal pH level depends on what species of fish is in the aquarium.
