Ok, looks like I've found this SafeStep locally. Any links on calculating dosage? Or how to add to 10:1 mixture to what amount of water change water, how often?

I personally find that adding 1 cup of 10:1 Mg salts to 15gal of water change water made with IO that I change weekly keeps my tank around 1400ppm. The reef chemistry calculator http://reef.diesyst.com/chemcalc/chemcalc.html works relatively well for calculating a starting point. This article might help too.

Thanks. So 3 cups in a 50g water change is a good starting point? I guess if I'm going to dump stuff in my tank, I should read all the articles, right??

I'm not using it in a reactor, just want to dump it in my water change batch. Easier that way.

10:1 MgCl2 (SafeStep) to MgS04 (Epsom salts) dumped into my water change container. Been doing that since late last fall.

So, you finally decided to start adding Mg....

Same amount as Russell?

And ya, thought I'd play with it, see if it matters.

Reading is always good and 3 cups in 50gal is conservative. Mg salts aren't nearly as potent as Calcium Chloride so although it seems like you're adding a lot it actually isn't that much. As others have indicated the Magnesium Chloride Hexahydrate actually contains a lot of water. Its also really good at absorbing even more water from the atmosphere so once you open the bag either tie off the top or move it all to a well sealed bucket or you'll be dealing with a monolithic block in no time.

My Mag is Dead Sea Works(from the Dead Sea in Israel) which is Tech grade. I have been using it for at least 3 years with no problems. While we are on the topic of USP or FCC or Tech Grade chemicals. What do you think the $35 buckets of IO salt are made from... they are too cheap to be USP grade.

Brad, if it's M. C. Hexahydrate, you'll want to mix 5cups of it with 3cups Epsom salts into RO and after it's mostly dissolved top it up to 1 US gallon/3785ml
This will last you quite awhile, once your Mag is up where you want it

For dosing go to this Reef Chemistry Calculator and select Randy's Recipes 1 and 2 versions A and B
Don't miss the top window where you add your system volume if you want the calculator to actually work

Even though you have a Calcium Reactor, info on the Recipes is here;
An Improved Do-it-Yourself Two-Part Calcium and Alkalinity Supplement System
It'll tell you more about the Mag portion the Recipe

Edit: I didn't realise Randy wrote a separate article just for Mag
Thanks for the link
