So...... what does that mean? Is this high/low/on target?

You are shooting for a dKH of between 8 and 11, so your 6.72 is somewhat low.

Going back to your original post, I am wondering by what means are you testing pH? Do you have a meter or are you using a test kit? If using a test kit, please explain how your particular kit works and the range of pH that it will test, so we are not guessing your pH, but know its' actual values. Without actual values, it is foolish (and dangerous, even) to suggest a course of action.

Remember, that pH is lower just before lights on and higher just before lights out and these are the values to be looking for. For instance, this morning in my 67g, pH was 8.24 and last night it was 8.47, using a Pinpoint pH probe connected to a Hanna Instruments pH Controller.
