pH (Acidity)
General Guidelines:
- Ensure that the test tube is clean before use.
- Clean the tube directly after use.
- Take the volume of the water sample as precisely as possible.
- Keep the dripping bottle perfectly vertical during dropping.
- Take care that no air bubbles are included in the drops.
Test procedure:
- Take a water sample of 5 ml.
- Add 5 drops of pH-test fluid
- Shake test tube.
- Determine the pH-value using the colour chart included.
The ideal pH for a marine tank is between 8.0 and 8.4. In case of a low pH,
add Colombo Marine KH+ in order to increase it. A higher pH is rarely
encountered; however should this be the case, you can lower the pH by making a
water change; always check the pH of the fresh seawater first!
For judging the colour of the water sample after adding all the test fluids,
proceed as follows: put the test tube on the included colour chart and look
through the tube on to the chart from directly above it. Do not look in direct
sun light, but at indirect light. Compare the colour of the water sample with
the colours on the chart. The closest colour shows the corresponding value.
Generally the colours of the sample and on the chart will not be exactly the
same, as values in practice will always be between the standard values, and
thus a mixture of both consecutive values. Therefore, one should estimate
between which colours the sample really lies.
