| | Re: API KH test kit - Anyone with experience? Measuring CO2 Amounts
Im not sure if you are tying to make a certain dkh reagent to add to a drop checker or if you are trying to use your pH and kH to determine what the levels of co2 are in your tank.
Here is what I can say about both scenarios.
If you are trying to make a specific dkh reagent yourself that is fine. I tried my hand at it and became extremely frustated by the process and just ended up purchasing a lab certified soloution that I know 100% is accurate.
Now if your trying to determine your co2 levels by using the pH/kH chart that is just not a good idea at all. It has long been proven that this method of trying to determine co2 saturation is horribly inaccurate due to so many different buffers (driftwood/reactive substrate/hard scape/co2 injection/and any water parameter altering products you could be using like peat and so many other things) that could be in your tank water that will throw off the reading/result you get you actually have a better chance guessing or pulling a ppm out of the thin air than using the pH/kH chart.
