Those are both OK, but it would be nice to get the pH up a little. Kalkwasser drip is the easy answer. Remember that there are three legs to the pH tripod: Alkalinity, calcium and magnesium. Obviously, it's not quite THAT simple, but these are the three levels you'll want to watch. If you're able to keep calcium above 400ppm, you're doing OK. And you'll hear alkalinity (dKH) guidelines anywhere from 8-12 dKH. I prefer 11-ish. Magnesium should be 1250-1350ppm.
