My tapwater is softer than that and I use it unmodified for all my fish including corys, danios and tetras - the pH is a bit variable 5.0-5.8 swinging daily but blackwater Apistos thrive in it. I've found it a bit too acid for Borelli and the sex ratio of Cacutoides is skewed to 100% females (although I don't know if thats pH or temperature related) just to add to the discussion anyway...
