Calcium levels driving me nuts

[Quagmire]

I would have to agree with mg sugestion.IMO mg is as important as ca and alk,its all part of the mix to get good perameters.Get a mg test kit,dont take someone elses guess as to how much to put in your tank,each tank will use a differant amount of mg,ca,and alk.So a guess although working well on one tank may not work well on yours or anyone elses.You will always use up some mg so better to have the test kit so you can stay ontop of it.BTW I picked up some of that new salt from Golds called Oceanpure Pro,very high mg around 1470ppm.the last time I tested it.
