Magnesium settling in dosing reservoir

[catchandreleas]

So I just set up a dosing pump, I'm using a glass container for the additives.

I filled the glass container with brightwell magnesium yesterday and this morning it has settled to the bottom of the solution. The bottom 3/4" is cloudy and thick, while the top is 6" is clear.

What have I done wrong here?

I put some small pumps in my dosing containers, to keep the solution mixed.

I figured with a pre mixed solution such as this it wouldn’t be required. I never had to shake the bottle or anything when I added it straight from what is was sold in

I did add the small amount left of my Red Sea magnesium to the brightwell when I filled the dosing container. Perhaps it did something? Seems unlikely.

If the solution is too concentrated, cooler temperature can precipitate salts.
Try diluting with ro water, like 3:1, see if it clears.
Also, if it is basic from residual NaHCO3 it will ppt, add acetic acid to solublize.

Mixed it 50/50 with RO and it's crystal clear. Great call. Thanks for the help!
