The higher the reading, the harder the water.

It doesn't really matter as long as you have some. 2dGH perhaps a little bit low - I tend to add RO Right to my RO water during water changes to give me a dGH of 3-4 - however if your plants are fine and showing no problems then I wouldn't worry. Some plants, such as Vallis, may suffer in very soft water though.
