Sera PH Test Solution, pH 4,0 (100 ml)

The sera pH test solutions are test solutions for the calibration of electronic pH measuring devices.

Determine water values
pH value, carbonate hardness (KH), ammonium and nitrite are among the most important water parameters. Extreme deviations from the target values can suddenly become an acute danger to life. Whenever the appearance or behavior of the fish becomes noticeable, or other peculiarities (e.g. sudden death of the aquatic plants) in the aquarium are noticed, the basic water values should be checked first. The easy-to-use test strips can be used for routine control. For more precise results, we recommend testing the sera aqua-test box in a sturdy plastic case. Total hardness, nitrate, nitrite, phosphate, iron, copper, chlorine, silicate and oxygen are also known to the experienced aquarist as average values in his aquarium. Checking these values now and then is usually sufficient. If there is suspicion (e.g. signs of poisoning, algae problems, shortness of breath), these parameters should be examined more closely.

The various sera test solutions (pH 4.0 / pH 7.0 / pH 9.2) are suitable for the calibration of all electronic pH measuring devices.
