The 2 Part Calcium & Alkalinity Total Package with Dosers includes everything you need to make your own 2 Part Solution and begin dosing. Simply measure the dry material with a household measuring cup and mix with water in the included gallon jugs. This kit will help maintain Calcium, Alkalinity, and Magnesium parameters in the tank in easy once a day doses. It also makes it easy by automating the 2 Part Solution using a dosing pump to make your daily additions. Your corals will be healthier and grow faster.
Each Kit Includes:
- 2 BRS 2 Part Dosers 1.1 mL per minute
- ½ or 1 gallon of Calcium
- ½ or 1 gallon of Alkalinity
- ½ or 1 gallon of Magnesium Chloride
- ½ or 1 gallon of Magnesium Sulfate
- 3 clear PVC 1 gallon jugs with caps
- (2) 1 ounce dispensing pumps
- (2) 100 mL cups for measuring liquid solution
- 1 Funnel
BRS 2 Part Dosers are ideal for automating 2 Part dosing. Our peristaltic pump has an extremely accurate 1.1mL per minute flow rate. Silent operation. The pump utilizes a unique system that attaches the drive shaft at the bottom and top to eliminate shaft wobble. Precision two roller design extends pump life and will not back siphon. Not for continuous use.
Use the BRS Reef Calculator to calculate dosage amounts. For more information on how to use the 2 Part Solution click here.
Perfect 2 part solution By Kenm on 8/27/2017Kenm would recommend this product to a friendThis kit provides a perfect solution for your 2 part (really 3 part) needs. I use a reefkeeper lite basic to control the pumps and it works out just great!
BEST VALUE OUT THERE .. HANDS DOWN. By John on 7/18/2017John would recommend this product to a friendGreat product comes with everything needed to set up except timers . Easy installation , takes a few days to dial in for your specific needs . I would recommend this to everyone that gets tired of manually adding calcium to your tank.
Great Stuff! By Rgdn on 6/3/2017Rgdn would recommend this product to a friendI really appreciate the effort BRS makes to make awesome reef aquariums possible for people without a chemistry degree or unlimited funds! This product has worked flawlessly for me. The directions were simple to follow and with the help of the BRS Reef Calculator and a single BRSTV video, I had my automated 2-part setup dialed in in no time!
Working Great By sds72 on 3/24/2017sds72 would recommend this product to a friendThe dosing motors are very precise, tested my schedule into measuring cups for first week to verify. Right on the money! The two part solutions are easy to work with and package comes with enough to keep me going for long time. Corals doing great!
I will never run out of 2 part!! By Brad on 10/17/2016Brad would recommend this product to a friendThis is a great package and in the long run will save money. The only thing is the dozers in my kit put out a little more than 1.1 ml per minute. I adjusted the timers accordingly and it's all good. No more spilling 2 part dosing by hand. You will like this product.
Easy But Not As Described By Jeffrey on 12/30/2015Jeffrey would recommend this product to a friendThis is my first dosing pump. Very easy to set up and get working, but calibration showed them to be 1.8 and 2.0; not the 1.1 described. Calibrating them before running on the tank is absolutely necessary!
BRS auto dosers By Rich on 12/27/2015Rich would recommend this product to a friendWell I waited a long time to get these dosers it should have been the first item to get, a must have item for the reef tank, works well and priced right when on sale thank you BRS.
Great Product! By Hitch on 9/20/2015Hitch would recommend this product to a friendWorks amazingly! My corals have been doing great and I feel I have taken the last step to get my tank to support the harder SPS corals. Paired it with the Reef Keeper plus and would never do a tank without this system again.
Best upgrade I have done for my tank By William on 9/6/2015William would recommend this product to a friendGreat deal and super easy to use. Corals really seem to like it.
Great Dosing Pumps By NateP on 8/19/2015NateP would recommend this product to a friendI'm pretty new to dosing and have been really impressed by this package. The dosing pumps were really easy to mount and get set up. BRS did some videos on how to program the apex controller that made setting up the program to time the outlets pretty straight forward. The included instructions and supplies made mixing the different solutions pretty easy. I'm still measuring and adjusting the dose to match what my tanks consumes, but overall I have been really pleased with the results.
Great package for the money By elwaine on 6/9/2015elwaine would recommend this product to a friendGetting the dosing pumps calibrated and the system up an running was easy. Very clear instructions and helpful video tutorial. The dosing pumps are quite good, but they are not as precise as pumps I've used in the past... pumps that cost a lot more than those that come with the BRS package. However, they are good enough to have kept my Alkalinity and Calcium rock steady for a month, now. So they provide all the accuracy I need. I would definitely buy this again. I see no reason to spend big bucks on very precise pumps when these do the job perfectly.
Great Value By brian on 5/6/2015brian would recommend this product to a friendThis is my go to kit for dosing. Includes everything you need to automate 2-part dosing, given you have a controller (or timer). The dosing pumps are fairly accurate (+/- .1ml/min), and durable. The only con would be trying to figure out the Captcha in order to submit this review.
Ask a question
If this package makes more than 1 gallon how much does it make?
The 1 gallon package contains 1 gallon of each dry reagent. How many gallons of solution this makes depends on the particular ingredient but your looking at about 8 gallons of alkalinity and 6 gallons of calcium in most circumstances.
Really just about any of them would work but the easiest is the Red Sea supplements because they have simple dosing recommendations based on calcium consumption (if you raise your calcium by X, add Y amount of trace elements).
It sure does. The pumps themselves come with a little over 15ft of tubing each.
Magnesium declines very slowly and generally only needs to be added once a month or sometimes even less so most folks opt to save the expense and just dose the magnesium by hand when necessary.
We find it best to let the mix settle after mixing for around 4-5 hours, going back and checking the mix and if salt is still present you can mix it up regularly 2-3 times per day until the solution dissolves.
These are 5.5" x 5.5'" x 11.5" Feel free to let us know if you have any further questions!
Our system will work great in conjunction with the red Sea coral color program and comes highly recommended on larger tanks where trace elements are not replaced with large water changes. This is a great (affordable alternative which will give you control over the amount you are dosing in.
The 2 Part total package includes soda ash for alkalinity and will both raise/maintain your alkalinity and support a higher pH as well.
The solutions must remain seperate from each other until they are added into the aquarium. You will want individual dosers for the calcium and alkalinity (which two are included in this package so your covered there). Most folks dose the magnesium by hand as it typically only needs to be added weekly or monthly, compared to the daily dose on the calcium and alkalinity.
Its best to dose them at separate times to high flow areas of the tank, though if dosed slowly to separate high flow areas of the tank its generally not an issue if you need to dose them at the same time either.
The BRS dosing pumps are compatible with the Reef Keeper system, just be sure to use outlets 1 and 4 with low voltage dosing pumps.
That would be the best way to do it, though if they were running for the same amount of time (which would generally be the case) you could run them off a timer with two outlets as well like our Hamilton Digital Timer. That said though, might be worth picking up a simple controller like the Reef Keeper Lite Basic. By the time you add up the cost of 4 timers its basically paid for itself not to mention the temp probe and controller functions themselves.
You can use either Sodium Carbonate (soda ash) or Sodium Bicarbonate to supplement Alkalinity. The main difference between the two is that Soda Ash will raise your pH along with Alkalinity and Sodium Bicarbonate will not raise pH. Soda ash will also raise the Alkalinity more by volume so you will need to adjust dosage based on which one you choose.
If your system naturally runs at a high pH (above 8.3 - 8.5) I would go with Sodium Bicarbonate but otherwise Soda Ash will help bring up your systems pH.
I hope this helps!
Have a great day :)
