Mr D. –
I’ve noticed a big difference in my corals after daily dosing of magnesium. They obviously needed a bit more. Very happy

Did you accidentally fill your aquarium with regular water softener salt, and later realize that Magnesium is very important in saltwater?
Cheapest way to bring that bad boy right back up.

I have had a reef tank for about three years now and the SeaChem products is all I ever dose with. They dissolve easy and are a great price. They are also made right in Georgia so it is a Made in USA product which is great.

Great magnesium been using the supplement for years in my reef tank

I am dosing my tank with Sechem Reef Advantage Magnesium. I was taken back by the amount needed to raise my Magnesium just a little bit. So for example, I am raising Magnum from 1200ppm to 1375ppm for my 120 gallon system requires nearly a kilogram. That Is basically the entire contents of this jar. I think next time, I will order an even larger sized jar.
You will find a handy calculator for the Seachem product dosing if you search Google for the JDieck Reef Chemistry Calculator FV.

This is by far my favorite magnesium supplement and one of the cheapest ones to use. Personally I don’t like using a liquid form of anything I’ve found it to contain a lot of other “harmful” things In it. I just mix this up with fresh RODI water and make my own liquid form.

Not a lot to say , it’s the mag I use I’m my reef. It’s stable and works very well

It does exactly as it was made to do. If your dosing then I would recommend this. I’m not sure what happened but my last box of Reef crystals(orange) had no magnesium so I had to buy this.

Very necessary supplement for reef because it really created an seawater

I dose Reef Advantage Magnesium in my topoff water. It dissolves easily and there is never a precipitate. Once I tried Reef Advantage I have never used a liquid concentrate since. My Magnesium levels remain in a very narrow range around 1300 ppm. I use a lot of SeaChem products and trust this brand.
