That's good. On the pH, this will lower as the GH/KH lowers but the latter are still significant enough to have some buffering effect. As the organics accumulate in the aquarium from fish and feeding, it may push this down sooner, but it all depends upon the GH/KH. The GH is the important parameter for fish, and once that is down for "x" fish species the fish will have less trouble over the pH provided it is not fluctuating around (it shouldn't be).
