Diana If you need to dose a fair amount of KNO3, then the K is probably enough.
In my high stocked tanks I do not need to dose much N, so I use K2SO4 for the K, based on plant deficiency symptoms.

BruceF KNO3. Probably you won't need more potassium. Some people skip the no3 part and use KCL instead. (No Salt) Or KH2PO4.

let's.get.tanked Synthetic urea is created from ammonia and co2. When nitrogen is mixed with urea it becomes water soluble. Urea is found in most plant and lawn fertilizers. Potassium nitrate is the source of mineral nitrogen and the urea is what lets the plants absorb it. Potassium (K) is a different element altogether.

question on ferts

This may sound silly, but i was looking at the Nitrogen on PFerts and it says it contains Urea and Potassium Nitrate. What is Urea and if it's potassium nitrate, is there still a need to dose potassium?
