Why does BRS recommend this?
With everything included to maintain Calcium, Alkalinity and Magnesium the BRS 2 Part Total Package is one of the best values for starting a 2 part dosing system.
Simply measure the dry material with a household measuring cup and mix with water in the included gallon jugs. These kits will help maintain Calcium, Alkalinity and Magnesium parameters in the tank in easy once a day doses or you can automate the 2 Part Solution using a dosing pump. Your corals will be healthier and grow faster.
Use the BRS Reef Calculator to calculate dosage amounts.
All supplements meet strict BRS quality standards.

The best 2 part system! By wendell on 12/4/2017wendell would recommend this product to a friendBeen using this 2 part from brs for 3 years now man what a money saver ! Everything included in package all way down to funnel and dosing cups . very good quality I trust my sps tank to this product !
Cheap By Salty on 11/17/2017Salty would recommend this product to a friendCheap way to maintain your tank
Great product By TshaisVang on 7/19/2017TshaisVang would recommend this product to a friendI love to use this 2 parts dosing it does help to grow my corals and help keep my coraline algae
The only thing i put 4 stars because this 1gallon set are not equal mix after you done with the Calcium you still had quarter of Alkalinity and quarter of Magnesium sulfate i wish they just give the same for 3 parts equally that way when you done all 3 parts are done at the same time hate to throw away other part or have to order other parts to finish it.
GREAT product and easy to use By Mike on 7/14/2017Mike would recommend this product to a friendI've been using this product In fact getting ready to do a re order.
Good kit, dispensers suck By Jeff on 7/11/2017Jeff would recommend this product to a friendThe kit as a whole is awesome. The dispensing nozzles could be improved. If they were 90 degrees it would keep the spills down. If you don't have the cup perfect, a good pump will shoot liquid over the cup and onto the floor. Also, liquid gets retained in the nozzle and drips out later. Its easier to just put the cap on the bottle and pour into the measuring cup.
Great product By Jay on 6/15/2017Jay would recommend this product to a friendVery easy to mix the parts , comes with a measuring cup , and a dispensar for the gallon bottles . Use the brs calculator , it will tell you how much to dose and that's it ! Literally takes 1 min to dose calcium,Magnesium or Alk
Ease of use By statru362 on 4/7/2017statru362 would recommend this product to a friendI don't know what is top of the list when it comes to qualities I appreciate most in the BRS 2 Part. Between the ease of use, easy to understand directions, very helpful videos, calculators that remove a lot of the guesswork, or the brilliant way my corals have responded to my delight since I started using it! I really wish when I originally ordered the 2 part, that I would have ordered the auto- doser at the same time because I wound up placing the order a week later.
Top notch! By Brian on 3/6/2017Brian would recommend this product to a friendReally easy to use and kinda fool proof. Really works great!
Solid dosing, solid price By brad on 3/3/2017brad would recommend this product to a friendYou can't possibly beat the value in this product. If you are contemplating purchasing, do it! Do it now! BRS has excellent videos explaining the usage and mixing, calculator is solid. Buy this now!
Simplifies mataining Calciium & Alkalinity By Rick on 2/23/2017Rick would recommend this product to a friendBRS 2 Part Calcium & Alkalinity and the dosing system has made maintaining proper levels very easy.
Easy to use By Mike on 12/8/2016Mike would recommend this product to a friendGreat so far, easy to follow instructions and online calculator make it fool proof. Only gripe, is it comes with 3 jugs and only 2 pump dispensers, why not 3 dispensers?

Assuming your using RO/DI water and haven't accidentally contaminated your solution (for example spilled something in it) it will basically last forever. It won't oxidize and being such a simple solution it doesn't have anything to react with to go stale.
That would be the best place to start.
Hope this helps!
Initially, I assumed you were referring to the unit of measurement "Cup," but inspecting the item list, it refers to the "household measuring cups" which are each 1/2 Cup in measurement.
So which is it? Cups or cups?
I am dosing 36 ml of BRS calcium and alK but staying at 410 and 8.1 at about 6pm. I dose calcium during the day and ALK at night. Should I be dosing that much for those readings? Also Once the solutions are mixed would the be ok being stored in a Florida garage? I Am looking for 450 and 9.0 to improve growth. I know that was a lot... sorry.
Weighing the powders instead of measuring in 'cups' just seems to be more exact.
(At least that's the way that I prefer.)
The weight by gram for Calcium will be 500 grams, for Soda Ash the weight will be 475 grams. This is the equivalent to the cup rating on the amounts. For Magnesium we recommend measuring out by cup instead as the weight of magnesium can vary greatly depending on moisture content. Feel free to let us know if you have any further questions!
Will I need to does strontium separately?
Ours will not contain the trace elements. Many individuals will add trace elements in separate forms when testing for the elements. Trace elements can also be added by larger water changes with a solid salt mix. Feel free to let us know if you have any further questions!
The magnesium goes down very slowly and is usually only dosed when you finish an entire gallon of calcium and alkalinity solutions. Considering for most folks this is a monthly occurrence at best, there isn't as much need for a dosing pump so people prefer to save the $80 but you can certainly pick a third up if you would like to automate that process. It can be found right here:
Thank you for reaching out to us with your question.
There is not a "best time" to test for calcium and alkalinity. I would recommend testing at about the same time of day each time you test and also testing before dosing.
Let us know if you have any other questions!
The 1/2 will have 8 cups of each element. This will make 4 gallons of Alkalinity, just under 4 gallons of Calcium and just under 2 gallons of Magnesium. Feel free to let us know if you have any further questions. (the 1 gallon will make twice as much)
With 8 cups in 1/2 gallon you will be able to make 4 gallons of Calcium, 3 gallons of Alkalinity and 2 gallons of Magnesium. Feel free to let us know if you have any further questions!
I decided to just put the two cups of Soda ash straight into the Mixing jug and add my RO directly from my RODI filter. As it’s comes out slowly I noticed the solution is HOT. Will the Alkalinity portion still be usable?
Here is the directions for mixing the magnesium chloride and magnesium sulfate:
Add 5 level cups of Magnesium Chloride and 3 level cups of Magnesium Sulfate to a one gallon jug and mix with RO/DI or distilled water. Let sit before use.
If you have any other questions please let us know!
In a perfect world for every 1 mL of calcium dosed, you should dose 1 mL of alkalinity solution. However depending on your salt brand of choice, the specific corals you have, the levels you keep your tank at, and many other variables that may change the 1:1 ratio just slightly. You will want to monitor, and test your levels for the first few weeks of dosing and use our calculator to get the feel for the rate that your tank consumes each element. Most people find that it is not an exact 1:1 ratio, but is pretty close.
If you have any other questions just let us know. Thanks!
Its a bit different with each, but assuming the 1g kit (large kit) there is 16 cups in a gallon so thats about 6 gallons of calcium chloride, 8 of the alkalinity solution and 3 of the magnesium solution but youll have some dry reagent left over.
The only difference between the Large and small is basically the amount of material included with the package. The total package small would likely be plenty for your tank to start with as your consumption won't be as high with the soft coral tank.
I am monitoring water quality with Salifert and Hanna.

Thats not a problem at all. The only double coverage would be if you wanted to use the reef foundation ABC (as that is what the BRS two part basically is). The other components though (Coral Nutrition and Coral Color) don't overlap with the two part though.
The magnesium is dosed far less often (usually months apart) and in a large enough quantity (20oz) that its actually easier to pour the solution then use the pump :-)
RO/DI water definitely qualifies as filtered water so that is not a problem at all and really the best option.
Once mixed up they will stay homogenous. No need to constantly mix or shake them (though it wont have any negative effect either).
