## Overview

Seachem Flourish Nitrogen 500ml is a premium nitrogen supplement delivering a potent 15,000 mg/L blend of nitrate and ammonium forms. Designed to maximize aquatic plant growth without releasing harmful free ammonia, it supports a balanced nitrogen cycle and is safe for invertebrates like shrimp. Ideal for millennial aquarists seeking a lush, vibrant planted tank, it works best when combined with complementary nutrients from the Flourish line.

## Description

Nitrogen is one of the main three macro nutrients (nitrogen, phosphorus, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the plant–preferred ammonium form. However, no free ammonia is released because the ammonium in Flourish Nitrogen™ is complexed and unavailable until utilized by the plants. Ammonium becomes available after conversion of urea (carbamide). Flourish Nitrogen™ also provides nitrate for those plants that can readily utilize nitrate as well. For maximum benefit, use with Flourish Phosphorus™ and Flourish Potassium™. Flourish Nitrogen™ is safe for invertebrates such as shrimp.

Review: Great products! - I have been using Flourish products and my aquarium has been improving a lot.
Review: Seems like it can be used to cycle while feeding the plants effectively - This includes nitrates and urea, so I think it will help the nitrogen cycle along as the urea breaks down while also providing the final nitrate product to help keep your aquarium plants alive. I'm trying to keep my old cycle going in a new/upsized 29g tank but currently all I have in it is some nerite snails and a ton of aquarium plants (and hungry emersed houseplants, basil, etc), so I need to add a lot of nutrients to the water AND maintain the cycle until I am happy enough with my tank's maturity to get some fish. Generally I add aquarium ammonia and a little bit of fish food to keep the cycle going, and also feed the plants with Aquarium Coop Easy Green and occasionally some micronutrient Seachem Flourish. The tank is so heavily planted, especially with the emersed plants and the Salvinia, that I struggle to keep the nitrates high enough to feed everything. This Seachem Flourish Nitrogen stuff allows me to directly feed the plants a little more efficiently without overloading the tank with micronutrients. I just repeatedly added a half cap and checked the nitrates an hour or two later until I got it at the level I wanted. Eventually I will figure out a good schedule, which will of course completely change once the tank is stocked, but regardless, this product is a useful tool for planted tanks.
