Bang - Thanks I've seen you answer some a lot of other post about this topic so I was glad to see you post. I've seen people say you need to bake it first but I was thinking since I just have a 75g reef set up I would be ok to not go the bake route. Let me know your thoughts. Thanks
Baking Soda is Bicarbonate. If you heat it (bake it) it will remove CO2 and become Carbonate.
Either is fine as an Alkalinity additive.
The difference is that if you add Carbonate, some of the Carbonate will absorb Carbonic Acid to become Bicarbonate. This will raise PH temporarily.
In the long term there is no difference.
