Yet another thread regarding low magnesium in reef crystals salt.

140.95 N8800685 $252.91 N8095646 My doctor foster smith purchases of reef crystals salt !

My magnesium is currently at 950 . I want it at 1300 ( the level of natural sea water) . the tank is almost 600 gallons now. How do I correct the problem? I called customer service and you offered me one "bottle" of M tech. I appreciate this, but will it fix my mag problem? According to the calculator below I need 3 GALLONS OF M TECH ( the customer service rep said I was WRONG). Please help me


On the phone the customer service rep also quoted this statment
There may be many different factors as to why the salt is testing incorrectly, such as inaccurate test kits, incorrect mixing of the salt, or moisture getting in to the salt bucket.

There are also numerous variables that can affect the actual process of testing besides the test kits. These variables may include temperature, salinity and age of sample, quality of source water, incorrect calibration, calculation errors, and incorrect techniques. Because of these variables at least a 10 percent variance is common service ."
What else can cause this LOW of a mag reading, but the 600 gallons of reefcrystal salts I used as well as the many water changes I have done with this salt?
