Baked or unbaked Baking soda

[sky007]

Hi,

I read that dosing the baking soda will increase the KH, but should I baked it or not? assuming my PH now is around 8.3. Heard dosing the unbaked one will cos the PH to drop and KH to increase and dosing the baked one will increase both PH & KH. Correct me if I am wrong.

Thanks

Baking soda is just the common name for Sodium Bi-Carbonate bakers use them as a leavening agents, which means they are added to baked goods before cooking to produce carbon dioxide and cause them to 'rise'.

Baking soda can also be used for household cleaning.

For our application, baking soda is mixed with RO/DI or Distilled water to increase/maintain KH. Using baking soda (Sodium Bi-Carbonate) can cause the temporary drop in the pH of the tank. But tanks with sufficient water movement and aeration can easily equilibrate the drop in pH.

You can also converts the Sodium Bi-Carbonate into Sodium Carbonate by heat and therefore reduce the risk of lower pH by spreading the baking soda on a tray and bake for 1 hour in the oven at 200°.

Alternative is to just get Sodium Carbonate rather than Sodium Bi-Carbonate.

Thanks bro, the reason I am considerating Sodium Bi-carbonate is because is cheap and can get from any supermarket. I will try and see how it goes and hopefully not experience too much swing in PH. Thanks for advice.

Supermarket is not cheap, if you want to get cheap Sodium B-Carb, you can try bakery supplies store such as Phoon Huat - these are food grade baking soda.

However, for convenient sake, why not just get from our sponsors whenever you are there.
