Magnesium Dosing

[EPo]

My question is when is the best time to dose/adjust magnesium levels. I do a water change once a week, typically on the weekends. At the beginning of every month I test my magnesium levels and adjust if necessary. My question is, say i am at 1320 and i want to be at 1350, when is the best time to add more magnesium. Before a w/c? after a w/c? or in the middle of the week so that it disperses before my weekend w/c. thanks

After a w/c.

Magnesium depletes so slowly, and doesn't impact things like pH, that it makes no difference when you dose it.

I actually dose my newly mixed saltwater since it mixes low.

Which brand?

Which brand?

Red Sea Blue...it mixes up between 1200-1230 which is at the low end of what I normally keep it at.
