The reef hobbyist's choice for monitoring aquarium pH.
Salifert pH Test Kit is accurate to approximately 0.2 pH units so you can monitor minute pH fluctuations.
A stable, high pH level is crucial for healthy marine aquariums, especially reef aquariums where low pH can affect the growth of corals and coralline algae.
50 tests per kit.
For marine aquariums only.
Range: pH 7.4 - 8.6.
Fill the test vial with 5ml of water.
Add to this, 6 drops of the pH reagent and swirl gently for 10 seconds.
Compare colors by looking through the side. For this purpose, hold the white part of the color chart against one side of the test vial and look through the opposite side. Best results are obtained by using natural daylight.
If the color is somewhere between two values, then the pH is also in between those values.
In case the pH is too low, the alkalinity might be too low. However, never increase the alkalinity to a value higher than 12 dKH or 4.3 meq/L.
