- BRS Bulk Magnesium Sulfate 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 Sulfate is crystalline heptahydrate and dissolves crystal clear.
Bulk Reef Supply constantly strives to provide the best additives possible at the best price. BRS Bulk Magnesium Sulfate is produced using only the best pharmaceutical grade material available and meets strict BRS purity standards. For best results, mix with BRS Bulk Magnesium Chloride as part of the popular 2 Part Calcium and Alkalinity solution as well as a stand-alone magnesium supplement. NOTE: You can really notice 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.

Good Stuff! By wob on 4/13/2016wob would recommend this product to a friendAlthough the product needs to be shaken quite a bit and takes a couple of days to dissolve, the corals have all responded well. It also mixes crystal clear.

Safe your self money and buy this in bulk over premix liquid Mg By Sean on 11/26/2015Sean would recommend this product to a friendWork better and safes money over buying the premixed liquid magnesium like kent.
The good stuff By LBK Reefer on 9/15/2015LBK Reefer would recommend this product to a friendDo not be tempted to buy a lower grade product from other sources. This is a pharmacy grade product that mixes clear. Some cheaper stuff is available but it us designed as fertilizer and is not worth the risk.

I recently bought magnesium mix for my new reef tank. Are magnesium mix and magnesium chloride/sulfate are the same? Do i still need mg chloride/sulfate?
Why do the Kalk/Calcium reactor instructions show using so much less Magnesium Sulfate than the two part mixing instructions?
When using Kalk or Calcium reactor the sulfate levels and chloride levels tend to vary from the amount present in 2 part. This is a reason with Kalk or Calcium reactors you will use a 7 cups Magnesium chloride and 1 cup Magnesium sulfate in the gallon of solution. Feel free to let us know if you have any further questions!
What is the shelf life after the mixing?
The mix does not have a shelf life. If stored in a sealed container to prevent evaporation it can last forever. Feel free to let us know if you have any further questions!
