what I (and others) have found is that fresh sand beds adsorbe Ca. I also found from my testing that the sandbed will also adsorbe Mg untill if finnishes binding all the free Ca on its surface.
this will cause a Mg crash which will also cause a Ca crash. I would recomend you get a Mg test kit or see if anyone in your area has one that you could use to confirm this. I went through this for 6 months untill I finaly bought a Mg test kit and found my Mg was at 800ppm. this level would only allow me to obtain a 230ppm Ca level and that was with my adding kalk and using a Ca reactor. Once I corected my Mg to 1300PPM my Ca went up to 450PPM. but do a test befor you take this as the problem. Steve
