    I have just bought myself some Brightwells Alkalin 8.3 KH Buffer Powder after using normal Bicarb for months now and find the instructions very confusing...wondering if anyone who has used it can let me know if I have worked out my quantities correct.

    The instructions are as follows :

    Create a stock solution by disolving 20 grams of Alk 8.3 in 236ml of fresh water, each ml of this solution will increase the alk in 3.785L of water by 0.36dkh.


    Now my Alk is sitting at just over 6dKh, I want to raise it by 1dkh am I correct in my workings as follows :

    to round it down 1ml of the solution will increase the Dkh of 1L of water by 0.95dkh.
    Therefore if my water volume is roughly 500L after displacement I will need to double the stock solution in the instructions to 40g in 472ml of water.

    This will then increase my Dkh in my tank by just under 1dkh if I add the total solution to my tank.

    Sound correct? I am just trying to figure out a base to work from for now and the future and if I am correct in getting 1dkh it will be simple to work out how much I will need from there.

    cool man, thanks...will give it a go at those measurements and see how it goes. Just a bit worried of raising it too much.

    Hmmm well that didnt work out as planned. Tested my Alk this morning and its sitting at 10dKh, went up 4dKh?? No ill effects that I can witness from it jumping so high.

    So it seems that 2tsp and 120ml is needed to increase my Alk but 1dKh

    Hi kunhardt...always use half the dosage when you using new products;)

    This will ensure that you dot overdose....rather safe than sorry.

    Lanzo, i did dose half the solution to start off with, it went up 1dkh and I thought ok, well if half does 1 then its fine to add it all to get it up to 8...hmmm i think most of the solution was sitting at the bottom :p

    just checking up on this stuff befor i use it also.
    sheesh this stuff is confusing it states to dissolve 20g/in 8fl oz and according to my converter on the cell phone (fluide oz is UK here)that translates to 20g/227ml
    and one must not exceed 10ml/20us gal(75l)
    is this right?
    I want to raise my alk from 6dKH to 7dKH
    also how soon after addjusting ALK can one test and see the results of the addjustments made?

    Amount in grams = Amount to change in dKH / (6.8/ (*nett liters of your tank*/3.785) )

    Example:
    Let say we want to raise the dkh of 100L of water by 1.

    Then its x = 1 / (6.8 / (100/3.785))
    = 1 / (6.8 / 26.42)
    = 1 / (0.257)
    = 3.89grams.

    Easy peasy.

    Dissolve the grams in some ro water and drip into the system.
