After a bunch more reading on the subject, (head hurts, it’s 2:30AM), I ordered some sodium nitrate.
Will be interesting to see how my tank responds .
Is there a valid concern with PO4 plummeting while dosing NO3 , affecting SPS to the point of RTN? And should one dose PO4 as well or is fish food rich enough in PO4 to keep levels elevated?
I think the macro algae is coming out . It has worked too well it seems.
