Testing your carbonate hardness (KH) and general hardness (GH) is enough.

Tanganyika cichlids:
10 - 14 dKH
12 - 20 dGH
7.5 - 9 pH

Malawi cichlids:
9 - 12 dKH
12 - 19 dGH
7.5 - 8.5 pH

Those are ballpark figures. These fish are ridiculously resilient and will
usually be comfortable and display their full colours in almost any
condition.

The KH is usually more important to monitor than your GH as the KH is your
alkali buffer for maintaining a high pH.

Again, if you miss the mark it is unlikely to phase most species.
