Dennerle Plant Care N 250ml
Dennerle Plant Care N is nitrogen fertilizer for demanding planted aquaria. Whilst nitrate is often considered bad for aquariums as too much of it encourages algae, a trace level is still required for plants. This is very useful in no/low fish stock with dense planting set ups and planted Shrimp tanks. 1ml per 100L adds 1mg/L nitrate.
