If the tests are correct and you need to add any of the foundation elements just increase the levels gradually/slowly.
I.e. If the Mg was 800 and you want to be 1310 or wherever your aiming for, dont just dump a load of powder in in one go. You increase gradually over days if necessary to prevent shocking anything. The maximum dosages are shown in the instructions certainly in the Red Sea elements but if your using another brand just check.
If you are using Red Sea foundation elements, Just have a re read of the instructions again to make sure your ok with everything. There in the boxes and also online and it's worth studying them to make sure your happy with there use.
One final thing, if your using their combined ABC+ this is different as it contains all the elements. I'm assuming above your are using the individual A B C's which you can add individually to achieve the correct level of each element.
