I have been testing for Mg, and dosing....up to now....but I'm just now going to stop. It has been conveyed to me that it is not necessary because I do not keep any SPS. Just LPS, softies and I have 1 clam, plus a handful of other inverts. I will continue to test for Ca and maintain that at ~325, but for Mg I have to answer...."No. I don't bother".
Cheers
