Dennerle Plant Care N - 氮

The dropper makes it easy to dose just a few drops into my 20-gallon tank, and my rotala has perked up within a week. Nitrogen is hard to get right without triggering algae, but this keeps leaf color deep green without any film on the glass.

My stem plants were yellowing despite good light and CO2—after two weeks with this nitrogen supplement, the new growth is a deep, healthy green. The liquid mixes easily into the tank water without clouding things up.

My floating plants were looking a bit pale, but after two weeks with this fertiliser the new growth is a much healthier dark green. I was nervous about adding nitrogen, but the dosing instructions made it easy to get the tiny amount right without risking algae.
