Baking Soda mixing formulas????

[aquaglobal]

Hi guys,
I have a quick question for ya:
I am adding dry baking soda to my tank at the rate of 3.75 ml's per day in dry form.
I want to convert this into wet form for a dosing pump. My evoporation rates are not too high, so the stronger the baking soda/ro water mixture the better.
Better yet, is there a saturation level for adding baking soda to water then mixing?
I suppose I have to experiment and test!!!! Any help and or formulas would be a great help!
Thank you:rollface: PS What do you guys recommend for a doser that will doe tiny amounts? Or, I guess a timer that will kick on and off in seconds??

Yes, my recipes for unbaked and baked baking soda in water are reasonably close to saturation. Any concentration less is fine, as dilute as you want it to be. Using these exact recipes allows you to use the reef Chemistry calculator to determine the effects of different amounts:

Recipe #1, Part 2: The Alkalinity Part

Spread baking soda (594 grams or about 2 ¼ cups) on a baking tray and heat in an ordinary oven at 300°F for one hour to drive off water and carbon dioxide. Overheating is not a problem, either with higher temperatures or longer times. Dissolve the residual solid in enough water to make 1 gallon total. This dissolution may require a fair amount of mixing. Warming it speeds dissolution. This solution will contain about 1,900 meq/L of alkalinity (5,300 dKH). I prefer to use baked baking soda rather than washing soda in this recipe as baking soda from a grocery store is always food grade, while washing soda may not have the same purity requirements. Arm & Hammer brand is a fine choice. Be sure to NOT use baking powder. Baking powder is a different material that often has phosphate as a main ingredient.

Recipe #2, Part 2: The Alkalinity Part

Dissolve 297 grams of baking soda (about 1 1/8 cups) in enough water to make 1 gallon total. This dissolution may require a fair amount of mixing. Warming it speeds dissolution. This solution will contain about 950 meq/L of alkalinity (2660 dKH). As mentioned earlier, Arm & Hammer is a fine brand of baking soda to use in these recipes. Be sure to NOT use baking powder. Baking powder is a different material that often has phosphate as a main ingredient.
