Zoobest Alpha Test pH 4 - 9

Water test to determine the pH value in the range of 4.5 to 9.0 - suitable for freshwater and saltwater

The pH value is one of the most important water parameters in aquaristics. In short, the pH value is a measure of whether the water is acidic (less than 7), neutral (~7), or alkaline (greater than 7). It is a logarithmic scale, i.e. if the pH value changes by one unit, the acid or base concentration changes by a factor of 10!

Please refer to the literature for information on the optimum pH range for your species and use the test to check that these values are being achieved. If this is not the case, there are several ways to manipulate the pH. These include

  • Adding CO2 to lower the pH
  • CO2 reduction by aeration to raise the pH
  • Filtration through peat, alder cones, oak bark and other acidic wood and bark
  • Increasing the carbonate hardness with Duradrakon KH-Plus (pH increase) or DRAK pH/KH-Minus (pH decrease)

pH Test Kit 4 - 9 Instructions for Use

  1. Rinse the cuvette several times with the water to be tested and fill with exactly 5 ml of water *
  2. Add 8 drops of reagent and swirl
  3. Compare the color of the sample with the color card by holding the cuvette near the color that appears closest and looking through the cuvette from above. 1 - 2 cm distance
    For best results, use daylight (not direct sunlight).

* The meniscus of the water surface must touch the 10 ml graduation mark exactly

Caution

Clean the cuvette after use, close the reagent bottle tightly and store in a cool, dry place away from light.
Keep out of the reach of children!
