Yeah, use the calculator on the bulk reef supply website Reef Calculator - Bulk Reef Supply

Couple clarifications:
1. The actual amount of baking soda you should have cooked is 2 1/4 cups, not 2 1/2 cups. The calculators that you are using are for a solution of 2 1/4 cups of "cooked" baking soda, made up to one gallon with RO/DI water.
2. Once you "cook" baking soda, it is converted from sodium bicarbonate to sodium carbonate....also know as soda ash. At this point that 2 1/4 cups is reduced to about 2 cups total volume.

Best to check but I think you're correct. Recipe 1 is baked baking soda. Recipe 2 is unbaked baking soda.

All this is good info but my question was is the dosing calculater dose for dry soda ash or liquid? I need to know how much of the liquid to dose in a 100 gallon reef to bring dkh up 1-2 dkh.

Mike, I just went to BRS’s reef calculator for alkalinity, and it gives you the option of picking the type of alkalinity additive you are using. I just did this for 100 gallon total volume and found the results for Two Part (liquid) and Soda Ash (dry) (other options are available), to be 71.4 mls and about 1 ½ tsp, respectively, to raise dKH one unit.
As is most things in this hobby, I would advise doing this slowly, especially with alk. I personally would pick some volume in the middle and slowly increase that by 5 to 10 mls per day until I got to the desired dKH.
Hope this helps

Yes, this is Randy’s recipe, which has the same equivalence as most (if not all) commercial alkalinity additives (as example, B-Ionic).

You can use the Calculator either way. Depends if you are measuring/making as you go, or if you are making a bulk stock solution to dose.
Personally, I would recommend using commercially prepared liquid (ready to use) reagents until you get a handle on the Calculator, fully understand Randy's "Improved recipes..." article, and have some good testing+dosing experience behind you. Brightwell is my fav for having vastly superior instructions on the bottles.
Make it as easy as possible on yourself during this phase.
Cost should be very small at first, so I would try not to worry about the cost difference at this point.

Just dose it by the tablespoon Mike. Much Much easier.

I'm a fan of BRS, but can anyone tell me why we are pimping their calculator so hard to someone not using their products? (Have I missed something?)
Their calculator is only a subset of the real Reef Chemistry Calculator anyway, which is the same software, but has more products indexed, different appearance.
FWIW, you can even copy and run the Calculator source locally in your browser instead of going online for it.

I believe baked baking soda is the same as soda ash. Which is what I use and is the same as Randy's recipe #1. I use 2-cups soda ash to one gallon Rodi. I just used the brs one because I haven't figured out which solution to use to this calculator. Now that I have, I'm using this calculator. Much easier and more information. Thanks for helping me sort this out.
