BRS Mag?

To all of you who use BRS two part. When you make the Mag how long does it take for all of the salts to melt. I mixed mine 12 hours ago and there is still 1/2 inch or less in the bottom. Thanks in advance.

 

Is it Magnesium Sulfate or is it Magnesium Chloride? Magnesium Sulfate can take a long time to dissolve without a lot of stirring/agitation.

 

+1 on above

also heating the water helps to dissolve it faster, I use a product primarily consisting of Mag sulphate and find mixing it with warmed RODI and then allowing it to cool before use
is a more effective way for me to use it

when I used it, I would add the mag to the water over several hours. I found if I added the mag first and then the water, I was never able to get it all dissolved. If I added water then add a small amount of mag and shake it up and let it sit it did better. But it is a lot of mag to disolve in such a small amount of water and takes a long time

 

Thanks to all. Came home from work and there was a little left shook it a little and sat it in the sun on the counter and it melted. Its amazing 20yrs ago we didn't do all this stuff for are tanks.

 

20 years ago you were considered a genius to you could keep SPS or LPS corals alive for longer than a year.
