Anglian water says that the drinking tap water contains:
13mg/l Nitrate
601µg/l P/l phosphorus
3.45mg/l Potassium
Now I assume the nitrate is 13ppm? Tell me if I am wrong.
What on earth does the Phophorus one mean? is it 0.6ppm?
Many thanks in advance. I am just working out how much is...
I just found this while doing my usual bored internet searches and it's quite interesting (not that I know how to interpret the results)
Turns out I have Very hard water at 21(Clark) 17 (German ºdH) What does this mean for me? Don't know but hasn't been a problem for me and I don't use...
Not that I use them but I thought this article I discoverd on another forum was quite good giving shelflife of various test kits from various suppliers:
