Hello, I will try to answer. If I am mistaken please correct me.

Not sure there is a proper GH, depends on what kind of plants you have. Some will grow better in soft water, some will prefer hard water.

As for me, my tap water is soft (GH of 2-3). I have 2 little calcareaous rocks in my 65G tank, that make the GH go higher (now it is at 6), for 2 reasons.

If the GH is not too soft (at least 3), there should be enough calcium and magnesium in the water for most plants, it is commonly belived.
If the GH is not too soft, the risk of pH fluctuations is less risky.

Forgive my english, it is not my native language.

Michel.
