Well be that as it may, that still does not explain why baking soda is a non-lasting pH raiser (I've used it many times in the past, I know), whereas the Alkaline buffer certainly appears to stabilize and maintain pH.
Seachem says it's usage doesn't raise potassium or phosphate levels, and that it is a "sodium bicarbonate based buffer". Those statements do not reflect or deal specifically with what other elements may be in the formula to make it an effective buffering agent, perhaps justifying it's value and therefore extra cost over a grocery store bought baking soda product.
