right..
how can i explain the calculations behind how many grams to add to achieve x ppm in tank etc?
he refuses to see the logic in it. Chuck's wrong, tom's wrong everyone is wrong...
he keeps insisting that the calculations of grams pr gallon, is off, because they do not take into account that kno3 is only 38% No3..
can someone explain it in nice & cozy words, so i can convince him...
he wants to add 6.4grams of kno3 every other day, to maintain a level of 5 ppm... but according to chuck's calc. if i add 6.4 grams i get 12,07 ppm...
I dont get his thinking...
This is his calc. translated by me..:
if we want 5 ppm in the 325L(85,3g) tank this will be the way to go:
5 * 325(85.3) = 1625 ppm
1625 * 2 = 3250 ppm
3250/ 1000 = 3,2g. that's how much nitrate we must add:
but seeing as kno3 only contains 38 % nitrate
we must add this:
100/38 = 2,6 * 3,2 = 6,4gram is what we should add.....
perhaps im tired/stupid/non-mathematical, but i cannot see his way of thinking....
