- Pharma Soda Ash 1-Gallon Mix - Bulk Reef Supply
Ultra-pure Grade Soda Ash for 2-part dosing in your reef tank!
Bulk Reef Supply 2-part additives are the perfect solution to replenish the intake of calcium and alkalinity coral consumes when it grows. Using only pharmaceutical grade ingredients allows you to keep a cleaner reef with fewer impurities, leading to faster growth and more brilliant coloration of your coral. All BRS additives mix crystal clear and do not leave any nasty residues or brown impurities behind like other calcium and alkalinity additives.
Three Sizes Available:
- 1 Gallon Mix (1 single-use pouch)
- 5 Gallon Mix (5 single-use pouches)
- 10 Gallon Mix (10 single-use pouches)
Each pouch is professionally weighed to make 1 gallon of Grade Soda Ash solution that can be used to accompany any dosing method or used with other Bulk Reef Supply additives for an easy to follow system of dosing. The BRS system uses a balanced 1:1 calcium to alkalinity ratio that keeps dosing simple and doesn't require you to be a math wizard. In most cases, the amount of BRS Alkalinity solution you need to dose will match the amount of BRS 2 Part Calcium solution required.
Mixing Instructions - BRS Soda Ash Liquid Alkalinity
Fill a 1-gallon container 4/5 full of RO/DI or distilled water and then add the entire contents of 1 pouch 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!
General Alkalinity Adjustments - For large additions, we suggest using BRS Pharma Sodium Bicarbonate
Create a 1-gallon solution by following the Mixing Instructions above and then test your aquariums current alkalinity level and using the BRS Reef Calculator input your current and desired alkalinity levels along with your total system water volume. Choose BRS Soda Ash Liquid Alkalinity (New Pharma Pouch) option from the drop-down menu and select calculate. The result will be how much alkalinity 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 1.4 dKH or less per day to not shock your corals.
Tip: If you are having issues raising your alkalinity, check to ensure your aquarium magnesium level is between 1200-1350ppm and that the solution is added to a high flow area of the tank.
Step 1. Start by following the General Adjustments instructions above to adjust your aquariums alkalinity, along with calcium and magnesium to your desired levels for your dosing regime starting point.
Step 2. Wait 5 days and retest your aquariums alkalinity level and compare the results to your starting point levels to find the difference. The difference between the starting point and the final reading is how much alkalinity will need to be replaced over the course of a 5-day span of time. We recommend testing at the same time of day as alkalinity levels can fluctuate throughout the day.
Step 3. Go to the BRS Reef Calculator and input your new desired level and your new current level along with your total system water volume. Select the BRS Soda Ash Liquid Alkalinity (New Pharma Pouch) option and then calculate. That amount will be the total solution needed for a 5-day span of time for your reef tank. To know your daily dose just divide that number by 5 (see example below).
Step 4. Replenish your alkalinity by adding the 5-day total to your aquarium and any other diminished levels back to your desired starting point, then wait a few hours before starting your daily dosing regime.
Step 5. Monitor and adjust daily dose as necessary. If your alkalinity levels are slowly rising, we suggest subtracting 10% per day until it is stable. If your alkalinity levels are dropping slowly we suggest raising your daily dose by 10% per day.
Example for 100-gallon aquarium:
Alkalinity Level Day 1 @ 8pm - 9.0 dKH (desired level)
Alkalinity Level Day 5 @ 8pm - 7.5 dKH (current level)
5-Day Alkalinity Requirement - 107.1 mL (provided by BRS Reef Calculator)
Daily Alkalinity Requirement - 21.42 mL (107.1 mL / 5 days)

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.
Great product and price By Allen on 1/27/2020Allen would recommend this product to a friendGreat product at a great price. Pre-measured amount makes it super simple to mix and use.
good product but dont like the zip lock. By Bryan on 9/9/2018Bryan would recommend this product to a friendI don't like the zip bag. It's been my experience zip lock lets in moisture and often rip at the zipper. I use BRS because it doesn't clump and mixes well. If I get clumps with the zip bag I'll probably go back to making my own.
I wish there was a maybe for the recommendation. We'll see.
Simple By Carmen on 2/15/2018Carmen would recommend this product to a friendMixes great, convenient. No other way to reef but with BRS additives!
Works for me By David on 10/31/2017David would recommend this product to a friendI use with CaCl and BRS dosers.
Great stuff By Anthony on 10/25/2017Anthony would recommend this product to a friendFound an easy way to mix 5 gallons at a time just drop a power head in the bucket and you are good to go.

Simple way to manage alkalinity By Eric on 3/24/2016Eric would recommend this product to a friendEasy to mix and dose and keeps my alk where I want it.
Soda By Sal on 2/15/2016Sal would recommend this product to a friendExcellent product highly recommend it.
In the past I was using sodium bicarbonate. If I switch over to sodium carbonate how much more or less should I use of this?
Soda Ash solution will be roughly double the concentration as Sodium Bicarbonate solution, in which case you would likely find that 1/2 your regular dose would be sufficient. We highly recommend using the Reef Calculator on our site to determine the right dose amount. :)
How much material is in each pouch ?
Have a very loaded 180. has been set up for 23 years. I have such things as a 16 inch diameter chalice. a 10 inch elegance and approx. 24 x24 x 18 inch square montiporas. I am adding your soda ash at the rate of 4 ounces a day 7 days a week and still have a problem keeping it up to 10. I keep mag at 1400 and calcium seems to fluctuage on a daily basis. does that seem an outrageous amount of soda ash to be adding? thanks so much for your time
Thank you for reaching out. I am sorry for the delay in answering your question.
4 oz would be a pretty large amount for a 180 gallon system. I would consider checking to be sure that you are dosing into a high flow area of the system and that it is not precipitating. If it is not, you might consider switching to a calcium reactor as opposed to 2 part to maintain alkalinity.
Please let us know if you have any other questions!
