Abstract
An apparatus is provided for adjusting the pH of water in an aquarium. A measured sample of the aquarium's water is combined with a chemical indicator. The pH of the aquarium is then determined. If the pH is too low, drops of basic fluid having a known pH are added to the sample until the desired pH has been achieved. The number of drops of base added is then converted to an amount of a secondary base, based on the volume of water in the aquarium. This quantity of secondary base is then added to the aquarium and the pH is thereby adjusted to the desired level. Similarly, if the pH of the aquarium needs to be lowered, drops of acid are added to the sample and the number of drops of acid required to bring the sample to the correct pH is converted to a quantity of a secondary acid to be added to the aquarium to the lower the pH to the desired level.
