I suggest investing some money in a liquid test set.
They are more accurate then test strips.
Plus i've seen a lot of cases, where the LFS tests the water and comes up with a conlusion like good or fine, while we think otherwise...
Readings are fine , the only thing strange is a kH of 0.
That wouldt mean there is no calcium whatsoever in your water.
Either that test is wrong, or you got to explain to me where you get your soft water from.
Our tapwater comes out of the tap at 3 o and i add kH+ to keep it at 7 o.
And 3o is cosidered very soft allready.
