Diy Magnesium solution.

Yates273 · Feb 20, 2020

Trying to make a diy solution for magnesium. I have the Epsom salt and found this at Home Depot for the magnesium chloride Hexaydrate part. It comes from the Dead Sea. Before I leave Home Depot with it, is it ok to use to make my solution.
I currently dose Randy’s 2 part recipe 1 for low ph. My mag has dropped a little and now I need to dose some. I prefer diy. Since it’s much cheaper. I am dosing a total of 50 gallons of water with an alk reading of 8.5 and calcium at 465. Currently my magnesium is 1250. TNX

I know some people have used stuff like this successfully. At my place of work I have to mop the floors hourly because magnesium sulfide leaves an oily residue that is slippery. Personally I would not use it.

If what you post is actually mag flakes then it is the same stuff used in the imporved diy two part system. You might check with manufacturer to see if it is 100%.

I can’t make out the sds so it’s difficult to give a better answer than @beaslbob. It’s likely ok but the devil can be in the details. Any copper or metal listed in the spec sheet might change the answer.

I’d probably try it, depending.

I use magnesium chloride from a local industrial chemical supplier. checked the assay at the manufacturer's quality control department. Basically is was over 99% mag and water and the rest had no copper listed. It worked fine.

50 pound bag was $20-30 or so.

After the initial raising of mag from 800 ppm to 1350ppm with Epsom salts, I only had to add 300ml of the mag part every month or so. (55g tank). So even if there is some nasties well below 1% it still should work.

So in this stuff is easily available from home depot at say $10 a bag or so and is 100% mag chloride, I would use it.

What should I be looking for on the SDS sheet. It does say Mag chloride hexahydrate % “proprietary” no other chemical

Randy Holmes-Farley · Feb 22, 2020

An SDS doesn’t include adequate info about purity. 100% ingredient A often just means that us the only thing they add, not how pure that product is. This product may be fine, and especially if you can track it back to the Dead Sea Works, I’d use it. Other brand may be more risky.

Thank you Randy. Since it states “pure magnesium from the Dead Sea” does that necessarily mean it’s safe? or there could be other reasons it would be dangerous to use. I made a solution and will use as per your recommendation for recipe #1. Thank you for taking the time to respond.

No, that is not a guarantee of purity for our purposes. It is just claiming that it is the only added ingredient. Taken at face values it is obviously false since it is only about 11% magnesium. Not pure magnesium, which would be a metal that burned in water.
