0 0 0. Baking soda (sodium bicarbonate) does get converted to Soda Ash (sodium carbonate) by heating....preferably in an oven. What occurs is the heat drives off a carbon dioxide converting the bicarb. to the carb. In baking applications, it acts like a "chemical" yeast, producing little bubbles in the cake/bread/whatever you're baking.
MikeTheNewbie said: I saw a video where they recommended a mix of sodium carbonate and bicarbonate for increased stability. They mentioned that the same approach is used by Brightwell Alkalin 8.3. I understand sodium carbonate causes a short term increase in pH and sodium bicarbonate a smaller but also short term decrease.
It’s best to make it into a gallon solution and dose it into sump slowly. Baking soda (sodium bicarbonate) aka:”arm and hammer”, 1 1/8 cup dissolved into a gallon jug of RO/DI water.
Reaction score. 2,026. Rating - 0%. 0 0 0. Instantly. The online reef calculator is pretty spot on. And a big kudos for using sodium bicarb and going through the effort of doing it the right way vs wasting money on those rip off, pre bottled two parts. and. Apr 29, 2021.
Well there is a technique that reefers are using to make a very strong glue for repairing items or bonding rocks which is to put some baking soda in the crease of whatever needs to be glued and then squirting CA on to the bicarb. This apparently hardens almost immediately and is supposedly stronger than glue alone.
Converting that into a dry weight ratio of the two compounds by multiplying by the MW of sodium bicarbonate (84) divided by the MW of sodium carbonate (106), we get 8.2 * 84 / 106 = 6.5. So a 6.5:1 ratio of grams of sodium bicarbonate to sodium carbonate should give a pH of around 8.2 when dissolved in seawater. Apr 29, 2020.
I am using brs sodium bicarbonate for the alk. tank is doing very well, sps coral growing. My daily dose 180mL of soda ash mix and 95mL Calcium mix with using Kalk solutions for the ATO (8 tsp per 5 gallon). Alk steady at 7.5-8.4 , Ca at 440 and Mg 1,300 with 7mL per day. Question: since I am about to run out my Sod Bicarbonate, should I try ...
The baking of baking soda (sodium bicarbonate) drives off CO2 (and water) and converts it into sodium carbonate. It then has a pH boost when used, which baking soda does not. Baking sodium carbonate in a kitchen oven will not do anything useful. I currently recommend about 400 deg F for an hour, since it can take time for a large amount to heat up.
A "standard" sodium bicarbonate solution is 1 1/8 cups made up to one gallon with RO/DI water, while a sodium carbonate solution is 2 cups (2 1/4 cups of sodium bicarbonate baked at 300 degrees for one hour results in sodium carbonate (ca 2 cups)), made up to one gallon with RO/DI water.
Here's my recomendation.....make up a solution of baking soda by mixing 1 1/8 cup s of baking soda with RO/DI water to make one gallon. Use a reef calculator to determine amount to add. I used the BRS calculator HERE to determine that 66 mls (2.2 ounces), would be needed to raise alk from 7.4 to 8.4.
