Unless you have some very specific issues for spawning, or maintaining certain species, your GH is okay. Like pH, it is best not to play with it, causing swings; stability is best.
Just as an FYI for those commenting about wells...remember all wells are not the same. There are many well supplied community water systems, where the water is treated just as in a city system.
The community I live in has a system supplied by 7 wells and supplies treated water. In addition, I have a well on my own property. Aside from chloamine in the system, there is some substantial differences in tests on both water samples.
I'll try to find the site link where you can see water results for most any area of the country and will post it here.
