Yes it can but it is often easiest to do rather simple tests
Like check the colour against tap water
or even watch the ph drop
sure they aint scientific or accurate
But you probably do it without realising anyway
DOC are often 'mixtures' somakes it tricky to know what to measure
and once you have some results that doesn't help
as other chems are not in 'related' amounts
yea I butchered explaining that
but it ain't so much like the relationship between Kh and Gh and Co2 and
stuff
It's more just the fish soup
and everyones is different
water clarity is a biggie
but even so tis no sure fire
easier to just water change
or call your local water supply guy and get him to explain how he measures
it
will be a fascinating call I imagine
LOL
