    all of the mentioned are correct just the buffer amount of each of them is different. 

    There is not one percentage that forms a buffer system the combination of Citric acid and Trisodium citrate forms the buffer and depending on the Variation of the concentration the buffer system can Buffer for more or less on the given ph Value.  so if you have ingredients that constantly strangle your ph like Urea for example you need more buffer if you don’t have any and just want to ensure a Slim line for the Specification or an Activ will only work at 5.4-5.6 you use only a smaller amount of both.

    But I would expect the same ratio of ingredients, e.g. 1 to 4 or something like that, but the ration is different…
