Additive Mixing Problems

[Chris Harbaugh]

Can someone give me some advice on how to mix calcium and Magnesium?? what I mean is I am mixing Red Sea Foundation A, B, and C. I have found the secret to Mixing Foundation B , but Foundation A(calcium) and C(magnesium) will not mix properly. I use only RO/DI water and I have added the powder slowly, fast, stir before adding and while adding but I am always left with a extremely large amount of powder that will not mix.. it is already time consuming mixing this up but the cost savings is substantial which is what i need. any advice or tips regarding this would be appreciated.


I have a 125g mixed reef with a 55 g refugium and a 30g mixed reef with a 20g refugium. A great lover of Tridacnid Clams which is why i need to supliment additive between water changes, especially Calcium and Alk.

Sent you a private message. See if it helps.

Are you trying to combine A and C, or do you mean independently, they will not dissolve?

I am not certain how Red Sea formulates these, but a normal 3 part (like my DIY) has a lot of sulfate in the magnesium part, and that cannot be mixed with the calcium part without precipitating calcium sulfate. That's the reason (the only reason) that the DIY is a three part rather than a two part. :)

No. I do not mix any together. The instructions say so. Plus RedSea web site warns against it also.. it is quite alot left over for me also plus i have checked the expiration date also and im well within the exspiration.

Expiration wouldn't be an issue. Try warming the solutions.

Yes sir. I have done that also..

I don't know what the issue might be then, aside from not following the directions with respect to volumes, or the wrong material in the package.

Warming it has always worked for me, maybe give it a bit more time. I will throw the comtainer in a five gallon bucket and fill the bucket with the hottest water I can out if the tub to fully bath the container in hot water for a half hour.
