Raising Mg

[tlo]

You do need a lot to raise it, dont raise it too quickly, as it can stress your corals. Just remember it is a salt and raising it a lot will also raise your sg. I found if you need to raise your mag by a signigicant amount it is better to add it either with a water change or at the same sg as you currently keep your system at.

I'll hook you up with some mag. crystals for free. I have tons extra and never use it. I'd rather give it away then let it continue to sit in my basement.

In regards to the link between Calcium and Magnesium, mag. facilitates the uptake of Ca. in SPS. So raising your Ca one day and Mag. the next can help you get things back on track. I used to dose Ca. one day, and Mag & dKH the next, one in the morning, one at night.

Michika, those crystals would be great. I can pick them up when I pick up the food.

Thanks!
