No, sorry I shouldn't have done that I was being lazy - what I meant to say
was my General hardness is 40ppm and I should add my Calcium hardness is
about 10ppm. I haven't had problems with these levels but I should point
out that some of the very experienced (and read elderly) learned gentlemen
on this list recommend moderate to high hardness and calcium hardness
levels for keeping and more especially raising.
One other point to note from our earlier discussions is the apparent
dependancy of fry on high Calcium levels (which would be indicated by high
Carbonate Hardness reading??)
