You can dose the Mg anytime between your other dosing. Just pick a time dead center between your Ca and Alk timers - day or night is fine as far as I know
And if you're not needing to add much (once balanced), you could get by with a cheap daily drip setup, or just dump it in
I don't even know anyone with a dedicated Mg doser ... but I'm sure there's lots out there
I know if I had to dose it I'd have another pump  |
Well, I did just buy a 3rd doser (50ml/min high speed type), so I could do that. But that brings me back to the question of what type of Mg to buy. I could not find that East Start stuff around here. And not sure if I can trust some of the ice melters that I saw online, as they don't list ingredients.
I guess I could just buy more of that Seachem Advantage Mg from J&L, but it is not cheap for the amount I would require on an ongoing basis.
