Can you mix chemical in the same container?

Hi,
My question is, can I mix below 3 chemicals together in the same container? Any chemical reaction i should worry about?

1. Red sea magnesium (dry), mix with water to last around 1 to 2 weeks
2. Red Sea calcium (dry), mix with water to late around 1 to 2 weeks
3. Kent super buffer dkh (dry), mix with water to last around 1 to 2 weeks

I am currently doser manuly by hand each day and testing all 3 bi-weekly.

it will be like if I can put them in the same container and dose by a doser.

thanks,
Frederick

Alkalinity will precipitate the calcium or magnesium. So you can't do that.

If the magnesium supplement is a very good one then it has mag sulfate in it. That won't mix with calcium.

There's a really good reason why everybody doses those three separately. It certainly isn't because we never thought of mixing them.

never a good idea to mix chemicals in general... rest David covered it.
If u decide to dose them into the tank. do them at separate times as well for same reasons stated above.
