For my tanks, it's easy for the NO3 to climb steadily
between water changes such that I end up needing to dose
PO4 but not NO3. This situation occurs in the fast grow
tanks, in which I do regular large water changes, one with
rainbows and congos btw. I suspect the NO3 would climb
unacceptably high in a relatively short time were it not
for the frequent water changes. The N in the fast tanks
doesn't come from my tap water; it comes from the fish
food.In the slow grow tanks, NO3 is needed varies depending
on how much fish food I provide. Unless I measure the
food, the amount is somewhat unpredictable. Your sense of
"a dash of this, a pinch of that" might be more accurate.
As a rule I tend towards heavy fish (fish food) loads. So
the NO3 levels aren't unexpected. What is unexpected is
that the PO4 levels tend not to keep pace with the NO3. I
guess fish foods have very little phosphorus these days --
or maybe it's all bound up in the organic phosphates or
soemthing like that.
