Salifert pH Test Kit
Salifert pH test kit is sufficiently accurate to monitor pH fluctuations of approx 0.2 pH units.
The pH value can have a major impact on the growth of corals and calcareous algae and on many biological processes.
If the pH is too low then the cause may be a too low alkalinity and/or a build up of carbon dioxide caused by insufficient aeration. A low pH can be corrected by improving aeration and by increasing the alkalinity to NSW (Natural seawater) value or up to approx 25% above NSW levels.
The pH should not be allowed to fluctuate more than approx. 0.3 units during 24 hours and should preferably be kept between 8.0 and 8.2.
The Salifert pH Test Kit can perform approx. 50 tests.
Directions for use:
Fill the test vial with 5ml of water
Add to this 6 drops of the pH reagent and swirl gently for 10 seconds.
Compare colours by looking through the side. For this purpose, hold the white part of the colour chart against one side of the test vial and look through the opposite side.
Best results are obtained by using natural daylight.
