Seachem Flourish Excel 2l

Seachem Flourish Excel 2L — Bulk Pack Of Bioavailable Carbon Source for Plants’ Photosynthesis, Tissue Building, & Cellular Growth In Large Aquariums

Seachem Flourish Excel 2L (SKU: 724861-458) is a bulk liquid organic carbon supplement designed for high-demand planted aquariums and commercial aquascapes. Carbon is an essential structural element required by all aquatic plants for photosynthesis, tissue building, and cellular growth. While plants typically obtain carbon from dissolved carbon dioxide (CO₂), gas injection systems can be complex, costly, or impractical for certain setups.

Seachem Flourish Excel is a premium aquarium supplement that functions as a bioavailable source of carbon for aquatic plants. Seachem Flourish Excel enhances growth and promotes a thriving aquatic plant environment. It is a widely trusted plant supplement for planted aquariums that provides plants with the essential carbon they need for photosynthesis and healthy growth, especially in tanks that lack sufficient CO₂ supplementation.

Rather than being a traditional fertiliser, Flourish Excel delivers a readily usable form of carbon that supports lush plant development, vibrant colouration, and strong root systems. Flourish Excel delivers an organic carbon compound that plants can absorb directly without relying on gaseous CO₂. It provides simple organic carbon chains that plants integrate directly into photosynthetic pathways, supporting steady growth and healthy foliage. It also helps reduce algae by giving plants the competitive edge for available nutrients. Additionally, Flourish Excel has mild iron-reducing properties that help keep iron in its bioavailable ferrous (Fe²⁺) state. The 2-litre bulk container offers excellent value for large planted tanks and commercial facilities.
