3 weeks since I tried the elevated magnesium method, I still have not s much success as I wanted to eradicate the green hair algae.
And worse still, some of my sps polyps are either not opening up like the orange digi shown below or stn from the bottom like my lime green staghorn.
Current mg level at 1695 and calcium at 410 as of today.
I think I shall just start lowering my mg already to normal levels and just bear with the gha by manual plucking.
