API GH & KH Test Kit

Tests for GH (general hardness) and KH (carbonate hardness).

These parameters are often overlooked but are essential for a healthy aquarium.

KH or carbonate hardness can have a direct impact on PH so it is important to keep an eye on this parameter.
KH will naturally drop over time and are usually replaced during water changes.
If your water change schedule is not sufficient then KH can drop which eventually will cause PH to drop. This can be very harmful to your fish.
A lesser known fact is that beneficial bacteria actually consume KH so if the levels fall too low then this can be harmful for the nitrifying bacteria in your system.

GH or general hardness is less important but still worth keeping an eye on.
Some species of fish require harder water such as Mollies and Guppies. Other fish such as Discus and lots of Tetras prefer softer water.
Whilst we don't recommend altering your water to aim for the "perfect" conditions for your particular fish, we do feel that keeping consistent parameters is fairly important.
Just like KH, GH will drop over time and regular water changes are needed to keep these levels consistent.

We would recommend testing once per month.

 

PH
Fill test tube with aquarium water to the fill line
Add 3 drops of test solution
Cap the test tube and shake
Immediately compare the results to the colour chart
If the reading is 7.6 then perform the high range PH test to ensure accurate results. The method is the same but you will need to use 5 drops.

Ammonia
Fill test tube with aquarium water to the fill line
Add 8 drops from bottle one and 8 drops from bottle two
Cap the test tube and shake vigorously for 5 seconds
Wait 5 minutes then compare the results to the colour chart

Nitrite
Fill test tube with aquarium water to the fill line
Add 5 drops of test solution
Cap the test tube and shake for 5 seconds
Wait 5 minutes then compare the results to the colour chart

Nitrate
Fill test tube with aquarium water
Add 10 drops from bottle one
Cap the test tube and shake
Vigorously shake bottle 2 for 30 seconds (this step is very important for accurate results.)
Add 10 drops from bottle two
Cap the test tube and shake vigorously for 1 minute
Wait 5 minutes then compare the results to the colour chart

When reading results you should choose a well lit area and place the test tube against the white background of the colour chart so that it is touching.
