Very low hardness, does the pH stabilise at 7.9 in the tank? Over here in Scotland the water comes out of the tank at pH 8.5 but soon settles down to about 7 naturally after whatever the water company does to the water (temp hardness?) goes. It is then easy to lower using peat. If you have the space you can pre-filter tap water through peat before adding to the tank.
