Reef Complete is not a balanced calcium alkalinity solution. You shouldn't be adding anything unless you are sure why you are adding it. You do not need to add magnesium if you have 1600 ppm magnesium.

Ideally you should be managing your calcium and alkalinity either by using a balanced 2 part solution, kalkwasser or a calcium reactor.

You might be better off to get your numbers in check to do several large water changes or better yet many many smaller water changes.

Once you have your numbers in check then you find a good way to manage your calcium and alkalinity needs.
