Just follow the dosing instructions for Flourish Trace... it's ideal 
for every tank! Just kidding ;-) For most tanks, yes, the recommended 
dosing will do the job (that's why we tried to formulate it to be 
easy to dose into the "average" tank, if any tank is truly "average" 
that is). However, it is still important to watch your plants and 
keep your eyes out for signs of deficiency or excess... then adjust 
dosing accordingly.

We do not put large amounts of macronutrients (NPK) into Flourish 
because the macronutrients requirements can vary quite a bit from 
plant to plant vs their micronutrient/trace element requirements. To 
provide them in a fixed ratio in a product would not allow the 
hobbyist to vary one vs the other as the case may be. So that's why 
we don't put it in Flourish. But yes, you can mix them together as 
you see fit, for your particular tank(s) without any ill effects.

Flourish Trace is just the trace elements (non organic) while 
Flourish is both trace elements and micronutrients (vitamins, amino 
acids, etc). In general, one typically only needs to use Flourish, 
however, in some situations Flourish Trace can provide an additional 
benefit if for example the trace elements are being removed at a rate 
substantially greater than the other components of Flourish. This can 
either be chemical loss or rapid utilization loss due to intense 
growth or just the differences in trace element uptake among 
different species. Basically it comes down to this: try it for a 
month or two, if you see an improvement, continue to use it and 
Flourish, if you don't see an improvement, then you can safely 
discontinue it.

Hope that helps to answer your questions.
