Mg dosing based on Alk consumptions

[jduong916]

If I remember correctly, you can figure out how much mg to dose based on how much alk your tank consumes? If so, what do I divide my Mg dosage by?

 

[Greenstreet.1]

I dose 16% a day of my total daily alk

Is that what it is supposed to be or is 16% what works for your tank?

I asked the same question a few weeks back. That’s what I was told it was by Randy and it has been rock solid think I may have even bumped my salinity a little (nothing big). Dosing 4ml by Hand every am.

Your welcome. Anytime

Depends, of course, on what you are dosing. My DIY 2/3 part uses 610 mL of the magnesium part for each gallon of the other two. That's presumably the 16% mentioned.

It also depends a bit on which organisms use the alk/calcium/magnesium, since it varies and coralline uses more magnesium than most corals. A typical ratio of consumption is:

17.5 mg/L calcium
1.5 mg/L magnesium
1 meq/L = 2.8 dKH of alkalinity

Ill shoot for 16%, it's your recipe I use for all three.

Sounds good.

Happy Reefing.
