That's nothing. Consider your tap 0 ppm then.

Yes.

Both fine. As long as you do water changes regularly you can get away with
less GH.

Water sounds good. Just do big water changes.
Add the K2SO4(after water change only) and KNO3 and traces(2-3x a week).

Not really. You could use some Equilibrium from SeaChem if you want a little
more Ca and Mg. Or use MgSO4 and Ca(NO3)2 instead of KNO3 for your NO3
source.
