- Pharma Magnesium Mix for General Adjustments - Bulk Reef Supply
Ultra Pure Magnesium Additive for General Adjustments in your Reef Tank!
Maintaining proper magnesium levels helps achieve the essential balance of calcium and alkalinity in your tank by preventing excess calcium carbonate precipitation. Not all magnesium additives are created equal and the largest factor comes into the sulfate to chloride ratio in the magnesium solution. For large adjustments, you will want to use a magnesium solution that has limited amounts of sulfate to keep your reef balanced, where for daily 2 part dosing or maintenance a larger amount of sulfate is required to keep your reef balanced.
Pre-Mixed - Makes 1 Gallon of BRS Liquid Magnesium Mix:
7 1/4 c. Magnesium Chloride : 1/2 c. Magnesium Sulfate
- Ideal for large magnesium adjustments
- No residue left behind
- Mixes fast and clear
- Designed for easy dosing
- Pharmaceutical grade materials used
Kalkwasser or Calcium Reactor Users
This is the preferred magnesium additive for your aquarium if you use kalkwasser or a calcium reactor. In most cases the magnesium media used in calcium reactors meets the sulfate requirements and does not become depleted.
Mixing Instructions - BRS Magnesium Mix Solution
Fill a 1-gallon container 1/2 full of RO/DI or distilled water and then add the entire contents of the package 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.
Pharma mg By Jellis on 5/5/2018Jellis wouldn't recommend this product to a friendAfter mixing per instr. with RODI and shaking for days the mix did not stay in solution. Tried to use anyway and mg simply precipitated out. Not sure what the problem is. Def not as advertised!
Awesome product! By William on 4/13/2018William would recommend this product to a friendI love the Magnesium powder mix but I love the calculator you offer on how much to dose even more.
I have been able to keep my magnesium at 1350 up from 1100 without any problems and again with the help of your dosing calculator it's super easy to maintain.
works as described By rogergolf on 1/22/2014rogergolf would recommend this product to a friendWell product works and price is right. I just wish BULK reef supply sold the product in BULK not just 1 gal mix
Great! By Matt on 7/4/2012Matt would recommend this product to a friendPrice and effectiveness usually get all the credit, but I'm going to give it to these 1 gallon portions on form factor!
No need for a funnel, no measuring - just fill your jug with water, snip a corner of the pouch and voila - the pouch is your funnel.
It's hard to put a price on that kind of efficient convenience! In addition, this one has a stronger tendency to clump than the other "2 part" ingredients in my experience, so buying single servings makes even more sense.
Important supplement ang very easy to use By james on 5/25/2012james would recommend this product to a friendIf you are two part dosing this is a must have. Very east to use, just mix with a gallon of RO water. The calculater does the rest. High quality, mixes cristal clear.
Great Quality and Value MG+ By Fridmani1 on 3/22/2011Fridmani1 would recommend this product to a friendMixes up crystal clear after it sits over night. No residue on the bottom. It seems to work stronger than the reef calculator indicates. I used about 1/2 of what the calculator suggested and I was even a little above my target of 1350. It has held that level for 2 months now. Much better value than those commercial supplements.
easy to use By Chris on 11/22/2010Chris would recommend this product to a friendthis is very easy to mix and to use.when the Magnesium has fully mixed it is clean and look like RO water. my fish and corals seem to be happier.
Whats the shelf life of these bags if theyre unopened?
Thank you for reaching out.
The shelf life on an unopened bag is essentially indefinite. Once opened, they will also last a very long time as long as no foreign material or moisture is added to the bag.
Please let us know if you have any other questions.
Have a great day!
