Magnesium ???

[tpayne156]

What is the best way of going from 1250 magnesium to 1450?

[HighlandReefer]

What's the reason for increasing your mag up to 1450 ppm, rather than mantaining the recommended say 1280 -1350 ppm? Seawater averages just below 1300 ppm.

Ok I did not know that. So now the ? Is from 1250 to 1300 and how to maintaining that?

I would recommend using a proper ratio of magnesium chloride and magnesium sulfate to keep the sulfate and chloride balance correct in your tank. The ratio you use will depend on what you use to supplement calcium with. You can buy magnesium sulfate from the grocery store as Epsom Salts. You can buy magnesium chloride from for example:

Mag Supplementing Recommendations:

Mag sulfate and mag chloride are both important when increasing and/or maintaining your mag level. The mag sulfate will increase your sulfate whereas mag chloride will increase your chloride in your water. The idea is to keep the sulfate and chloride in balance in your water column. This leads to using them in the proper ratio to maintain the proper balance.

Randy calculated the ratios to maintain the proper balance of chloride to sulfate. It will depend on what you are using to maintain your calcium with.

If you are using Calcium chloride (two-part) to maintain your calcium, then use:

5 cups of mag chloride + 3 cups of mag sulfate in a total of one gallon with rodi water. Mix and you can add the particles in the solution.

If you are using kalk water or reactors to maintain your calcium, then use:

7.25 cups mag chloride + .75 cups of mag sulfate.

If you want to bump up your mag level in your tank or you want to increase the mag level in your salt mix or natural seawater, then use:

7.25 cups mag chloride + .75 cups of mag sulfate.

This is perfectly balanced with what is found in sea water and does not take into consideration any additions of chloride from calcium additives.

If you are using reactors (and/or kalk water) and also supplement with calcium chloride, then perhaps a good ratio to use would be:

7 cups mag chloride + 1 cup mag sulfate.

Once you make the correct ratio mag mix you can use the Reef Chemistry Calculator to determine how much to add to your size system.
