So I am new to cichlids and I am setting up a new tank and I cant seem to get the water hardness to the correct range of what the water test says is normal for cichlids. My readings are as follows GH - 30, KH - 40, pH - 8, NO2 - 0, and NO3 - 0.

The tester says these numbers for GH and KH should be 180+ for african Cichlids. Is there a way to increase water hardness or is this test giving me wrong info? I checked the current tank my cichlids are in and the test produced the same results.

Thanks again in advance for any advice.

I usually focus on KH and shoot for 4 drops or more. You just need enough KH to keep your pH stable. pH=8 is already good. If your pH is in a good range and is stable, it is better not to try to adjust other parameters.

KH results can be expressed as # of drops to achieve the color specified in the test, dKH or ppm. The number of drops = dKH. KH=40 is about 2 drops? It is on the low side but if you pH is stable I would not make adjustments.

Are you using reagents and test tubes for the tests? They can be more accurate.

If your pH is stable, no worries. If you want more accuracy for peace of mind for some reason, reagents are better for all your testing. Not just KH.
