Aquarium Ph Tester
It is sometimes of the utmost importance to check the pH of the water. This is sometimes measured so accurately that a simple exposure to air will make a marked difference. That kind of calculation, however, is not necessary at all for the aquarist. You need only be interested in fluctuations of a unit or so. Neutral pH is 7.0. Acidity runs from 0 to 7.0; alkalinity runs from 7.0 to 14.0. The maximum tolerance for most tropical fish for any period of time is from about 6.0 to 8.0.
Certain indicators, such as bromthymol blue, litmus, and phenolphthalein, change color with a change in pH. These indicators can be so calibrated that by comparing the amount of change of any given dye—this comparison is usually accomplished by a color chart—you can tell the acidity or alkalinity of the water.
Chemicals are available separately or a complete pH test kit may be purchased. For more accurate measurements, electrical pH test meters are available.
Buffer solutions may be purchased to aid in the alteration and stabilization of the pH. Care should be exercised that the buffer does not harm the fish.
Your pet shop will certainly stock a variety of water test kits that are useful to aquarists. Many hobbyists consider that kits to measure water hardness and ammonia or nitrite level are essential for maintaining a successful aquarium.
