Once you establish a "sweet spot" for your unique aquarium environment, use the ratio numbers that work for you!

It is also noteworthy that these buffers only address pH and carbonate hardness and not essential mineral cations.
So please read this article for a more in depth explanation of the use of RO or DI water for aquarium use:


Back to baking soda, this is an old stand by method based on the fact that baking soda does raise pH and KH, the problem is there is much new research to show that calcium, magnesium, electrolytes and Redox play a more important role in aquatic chemistry than just pH or basic KH alone (which is another reason 'good old fashioned water changes' often help improve fish health).
If Baking Soda is used, I recommend using Wonder Shells or similar products (such as AAP/SeaChem Replenish or Aragamix) to added needed calcium and other important electrolytes.

If you have a very unstable KH level (drops rapidly), look into causes such as a large amount of decomposing organic material.
