I've got very hard water, dose fertilisers like theres no tomorrow and stock lightly so not a great comparison for Nathan but I'm not noticing any loss of GH and all water readings are very stable. I'm doing about one 20% waterchange every month or two and top ups at least once a week. My tank is supporting a lot of terrestrial growth so that probably helps:

I'm not sure its advisable but its definitely possible to keep a stable tank without a lot of water changes.
