Keep your reef balanced - Use with BRS Pharma Magnesium Sulfate
Maintaining proper magnesium levels helps achieve the essential balance of calcium and alkalinity in your tank by preventing excess calcium carbonate precipitation. Unlike traditional Magnesium Chloride additives when dissolved with BRS Magnesium Sulfate it will dissolve crystal clear with no undissolved salts or residue left behind.

Mixing Instructions - BRS Liquid Magnesium Mix
General Adjustments - Fill a 1-gallon container 1/2 full of RO/DI or distilled water and then add 7 1/4 cups of BRS Magnesium Chloride and 1/2 cups of BRS Magnesium Sulfate into the container. Secure the cap on the container and shake it for about 10 seconds to help start the dissolving process. Remove the cap and fill the container the rest of the way with RO/DI or distilled water. Give the container a few more shakes and then let it sit until all the salts have fully dissolved before use.
2-Part Dosing - Fill a 1-gallon container 1/2 full of RO/DI or distilled water and then add 5 1/4 cups of BRS Magnesium Chloride and 2 cups of BRS Magnesium Sulfate into the container. Secure the cap on the container and shake it for about 10 seconds to help start the dissolving process. Remove the cap and fill the container the rest of the way with RO/DI or distilled water. Give the container a few more shakes and then let it sit until all the salts have fully dissolved before use.
Knowing how much to dose is made simple using the BRS Reef Calculator!
Create a 1-gallon solution by following the Mixing Instructions above and then test your aquariums current magnesium level and using the BRS Reef Calculator input your current and desired magnesium levels along with your total system water volume. Choose BRS Liquid Magnesium Mix (New Pharma Pouch) option from the drop-down menu and select calculate. The result will be how much magnesium solution you will need to add to raise your aquariums water volume to the desired level. We suggest adding small amounts at a time into a high flow area of the tank, like a power heads output or a sump baffle. It is important to keep changes limited to under 100ppm or less per day to not shock your corals.
What is 2-Part Dosing?
As corals grow they consume calcium and alkalinity but to keep the levels steady in a reef tank requires the use of magnesium too, so it is more like 3-part dosing, to be honest. Reefers will use calcium chloride and soda ash (sodium carbonate) to maintain their reef tanks chemistry daily and add a magnesium supplement every couple weeks. Magnesium supplements are usually a blend of magnesium chloride and magnesium sulfate to help keep the sulfate to chloride ratio balanced in the aquarium. When starting a 2 part dosing system it is important to use a good test kit to establish a baseline. We really like using the Red Sea Reef Foundation test kit or Hanna Colorimeters for their accuracy and repeatability which leads to a much more stable reef and overall coral health. Stability is one of the keys to keeping a saltwater tank healthy over a long span of time and most reefers will set up an automated system that doses their aquariums needed additives daily removing repetitive (and forgettable) chore. There are purpose-built dosing systems like the Kamor X4, Neptune DOS, or Bubble Magus T-11 that are super easy to program and keeps everything in a compact package, but there are other options that many reefers prefer like the BRS 1.1mL dosing pumps that can be paired with a digital timer for precise and affordable dosing control.

good By Dr. Zoidburg on 11/19/2016Dr. Zoidburg would recommend this product to a friendI like the really fine grain size compared to fosters and smith. Makes using a funnel a breeze. Following the mix ratio and calculator the tests come up spot on.
Best bang for the buck By Shawn on 11/4/2016Shawn would recommend this product to a friendGreat product. Raised my Mag levels to the desired amount in days.
MgCl good stuff! good price! good service! By larry on 6/20/2016larry would recommend this product to a friendMgCl good stuff! good price! good service!
much easy to use than chunks supplied by others By Bill on 4/20/2016Bill would recommend this product to a friendThe relatively fine size and consistency of the magnesium chloride made it much easier to handle than the chunky form provided by the previous source. The plastic bottle is much easier to handle than their plastic bags, as well as more reusable.
Easy to use and works By Eric on 2/8/2016Eric would recommend this product to a friendLike the magnesium sulfate, easy to mix and use with the calculator. My magnesium is where it needs to be now.
Good product. By Squareface on 12/18/2015Squareface would recommend this product to a friendMixes well. Nice price.
Good a Stuff...a Buy the 5 Gallon! By LBK Reefer on 9/15/2015LBK Reefer would recommend this product to a friendThis is a high quality Procter that mixes clear. You will over time use it, so buy the 5 gallon size and save.
Must buy By Michael on 7/29/2015Michael would recommend this product to a friendI have had my wallet drained using other mag supplements due to having to use a whole bunch of product to raise mag 100 ppm. Not to mention all the left over particles and horrible to mix.
With BRS mag chloride I am impressed how it mixes easy with a small amount of water and is crystal clear. Used the BRS calculator with a very small amount to raise mag 100 ppm, couldn't be happier and knowing that the product will last for at least a year makes my wallet smile.
I was spending 20 to 40 dollars a month with other inferior product.
You will kick yourself for not buying this product sooner.
nice stuff By Damon on 6/10/2015Damon would recommend this product to a friendGreat product, easy to use and mix. NEED TO KEEP IT IN DRY PLACE! It picks up moisture very easily, even in the container and then it's tough to break apart.
