..but I'd be grateful if someone could help with the following.
When reading through the forum people refer to the GH/KH readings in single numbers, I'm looking to breed CRS and the suggested KH is 1-2 and GH 3-8. What I'd like to know is which calculation is generally used?
I have a Nutrafin KH/GH Test Kit and to test the GH I add 1 drop of reagent to 5ml tank water, the solution turns pink, then I continue to add them till it turns blue. Then I multiply the the total number of drops by 20 which then gives the General Hardness. For this example the total number of drops is 5 so the GH is 100. So far so good.
Then there is a conversion table on the back of the pamphlet where by you multiply the total by either 0.056 =dh°, or 0.07=Clark H°, or 0.1=fH°, or 1=hardness°, or 0.02=mEq/L. Now I assume its dh° so taken that the GH is 100 the dh° is 5.6. Do people then round up the number to 6? I'd also be interested in knowing what the other calculations are. Thanks.
