I will make it the way you have instructed until I can source a supply, but a certified standard would eliminate any mistakes I may make from the equation. |
Don't worry about mistakes right now. Use your KH test kit to see if the batch of 4 KH water is close to being that per the kit. If you are off even 20% it is still better than what you have now.
If you don't have a scale capable of measuring 6 grams accurately, you can mix a little baking soda into a liter or so of distilled water, check the KH of that with the test kit, and if it is very high, dilute some of that water about 4 to 1 with more distilled water and repeat the KH test. Once you get a KH that you can measure, you can dilute directly to 4 dKH using the dilution equation Tom provided. It will only be as accurate as yout test kit, but still that is better than any other method you now have. In a few weeks we should be able to buy the water already mixed and done accurately.
