- BRS Bulk Magnesium Chloride Aquarium Supplement
Maintaining proper magnesium levels helps achieve the essential balance of calcium and alkalinity in your tank by preventing excess calcium carbonate precipitation. BRS Bulk Magnesium Chloride is crystalline hexahydrate and dissolves crystal clear. These small crystals are easier to measure than larger flakes used by other supplements.
Bulk Reef Supply constantly strives to provide the best additives possible at the best price. BRS Bulk Magnesium Chloride is produced using only the best pharmaceutical grade material available and meets strict BRS purity standards. For best results, mix with BRS Bulk Magnesium Sulfate as part of the popular 2 Part Calcium and Alkalinity solution as well as a standalone magnesium supplement. NOTE: You can tell a lot about the purity of magnesium supplements when magnesium sulfate and magnesium chloride are mixed together. High quality/purity magnesium supplements will mix together crystal clear. When mixing lower purity supplements you will usually see white precipitation and sediment form especially when mixed together.
Bromide, Ammonia and Phosphate Free

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.

There is 16 cups per gallon. Feel free to let us know if you have any further questions!
The BRS Bulk Magnesium Chloride Aquarium Supplement is exactly that, straight Magnesium Chloride. We do not put any other elements in with it. If you are looking for a solution that contains multiple elements you may want to check out the Reef Foundation system from Red Sea, but if you are looking for straight Magnesium Chloride this is what you are looking for.
Most folks use a combination of magnesium chloride and magnesium sulfate when adding the magnesium to the aquarium. With a two part system its generally a ratio of 5 cups of magnesium chloride to 3 cups of magnesium sulfate in 1g of water. This is to help keep the ratio of chloride and sulfate ions as close to what they are in natural seawater as possible.
There certainly is no reason you can't use a dosing pump for your magnesium. Most folks just do it by hand though as it usually only needs to be dosed once a week or commonly as little as once a month.
The Mag. chloride 5 gal bucket weighs in at 30lbs.
Have a great day!
A cup of Mag Sulfate or Chloride is 8oz, right? So, 5 cups of Chloride are 40oz, as well as 3 cups of Sulfate are 24oz. That would make a gallon of solution, which are 3.78 liters of solution. To rise 100ppm of magnesium in a 800 liters tank, I would need 1704ml, that's what the calculator says. Which is the same as saying 18oz of Chloride and almos 11oz of Sulfate, aprox in the solution.
So, buying the bottle with 6lbs of Chloride and one of 4lbs of sulfate, should be enough to produce about 20 gallons (75litres) of solution, and rise 4200ppm a 800litres tank.
Am I right?
Everything is correct! In order to calculate how much you need to add to reach your desired level of magnesium you can ensure you test for how much magnesium currently is int eh system with a test kit.
