I regularly test my system for Alk, Cal, PO4 etc. My question is - If I am using the same salt mix (Pro Reef), dosing (All for Reef), and the parameters for salinity, Alk, Cal, PO4 are remaining level - is it safe to presume that magnesium is in decent shape too?
I am happy to pick up a Hanna checker for mag, but I have heard that mag testing specifically can be inconsistent.
Would love yalls thoughts on the topic.
