That is good news....but can I share my experience. I test much less (once a month) than I used to and my numbers can get pretty out of wack in that time frame (I shoot for 8dkh and 400ppm calcium). Its not unusual to see alk at 6dkh or calcium at 350ppm by the end of the month (keep having to increase the dosages).....corals have never been happier though. Im sure if it went on beyond this point I would have a problem but my tank has never been happier. Also note that the decrease in alk and calcium happens very slowly over the month...no drastic changes.
I guess my point in all this is maybe chasing that magic number every week doesn't really help (although I'm sure keeping the numbers good and stable can't hurt).
