WHAT IS pH?
Technically it is the measurement of the hydrogen ion concentration of a given sample of water. From this measurement it can be determined whether the water is acid, neutral or alkaline. The scale extends from 0 to 14. A pH between 0 and 7 is termed acid, and a pH between 7 and 14 is termed alkaline. The indicator in this kit has a pH range from 6.0 to 7.8 and is therefore suitable for most freshwater aquaria. At or below pH 6.0 the test sample would turn yellow. At or above pH 7.8 the test sample would turn blue.

WHY pH CHANGES
pH is not a constant factor and is subject to continual change due to influences like bacterial assimilation of waste causing acidity or calcium and magnesium compounds like shells or coral that cause alkalinity. Thus, under normal aquarium conditions, because of fish waste and unused food, the water would drift to acidity.

TYPICAL FRESHWATER CONDITIONS
Amazon River Systems – The water is soft, usually below 50ppm hardness and a pH between 5.5 and 6.5. Water in rainforest rivers is conditioned by leaf tannins, humic and organic acids. Some leaching of ground minerals also occurs. These conditions are natural disease inhibitors for fish. Such water is suitable for Tetras, Discus, Angels and Corydoras.
Use Aquasonic AMAZON WATER CONDITIONER to recreate these same conditions in an aquarium. The result is brighter and more active fish, with a high resistance to disease.
Central American Rivers / Livebearers
– Water is quite hard – 300ppm up to 500ppm and a pH of 6.5 to 7.5. Livebearers originate from varied habitats, such as rainforest streams, brackish swamps and even salt water inlets. Guppies, Swordtails, Platties and Mollies
find this water suitable, however they can be susceptible to fungus and bacterial infections from water changes, tank movements and catching fish. Aquasonic LIVEBEARER WATER CONDITIONER has been formulated to re-create natural conditions in your aquarium, fish bowl or pond. It has the correct balance of salts, natural minerals and trace elements, plus bacterial and fungal inhibitors to promote health and wellbeing.
Asian River Systems – Water is soft, mostly less than 50ppm and a pH from 5.0 to 7.0. Such water is suitable for Gouramis, Sharks, Barbs, etc. Aquasonic TROPICAL WATER CONDITIONER has been formulated to re-create natural conditions in your aquarium. It contains the correct balance of salts, natural minerals and trace elements, plus bacterial and fungal inhibitors, to promote health and wellbeing.
Cold Water Systems – Water in these systems have a neutral pH of 6.5-7.5 and suit species such as Goldfish & Kio-carp etc. Aquasonic GOLDFISH WATER CONDITIONER has been formulated to re-create natural conditions in your aquarium, fish bowl and pond. It contains the correct balance of salts, natural minerals and trace elements, plus bacterial and fungal inhibitors, to promote health and wellbeing.
