I use it in my planted tank continuosly with no problems.

It does not remove nitrites and nitrates directly, but rather it removes dissolved organics that would otherwise break down into nitrites and nitrates.

Its impact on trace elements and nutrients is minimal.

Yes, dosing Flourish Nitrogen will put nitrogen in the water which Purigen won't absorb.

Nitrogen is am element. You want to put nitrogen compounds in your tank so plants can use them. Nitrate is a nitrogen compound - NO3. However, it's better to use nitrogen compounds that are closer in structure to an amine group (NH2) which plants use to make plant proteins. For example, ammonium - NH4+.

Flourish Nitrogen is a blend of different nitrogen compounds, including potassium nitrate, ammonium, and guanidine.
