## Overview

Seachem Flourish Excel is a 250 ml liquid supplement providing bioavailable organic carbon to aquatic plants, enhancing growth especially in tanks without CO2 injection. It supports iron uptake by promoting the ferrous state, improving nutrient absorption. Ideal for use alone or with CO2 systems, it helps avoid pH imbalances but requires careful algae management and regular water changes.

## Description

Flourish Excel is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). The use of either CO2 injection or Flourish Excel does not necessarily negate the use of the other. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2 . The combination is particularly ideal for situations when continuing to add CO2 could result in dangerously low pH levels. Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).

Review: Bacteria and algae comes from this product | use wisely - Product is good but must imp is Bacteria and algae comes from this product. Make sure water will change on the 15-20 days while put time chemical on the water of aquarium.
Review: This is NOT a fertilizer. This is just liquid CO2. - Many people have doubts on the usage of this product so let me explain. This is a liquid CO2 and is useful for people who do not have pressurized or DIY CO2 injecting system in their planted tank. I used it alongside a pressurised CO2, and it gives decent results. However, please be careful as it also prompted Algae growth. Make sure you have some decent algae eaters in your tank before starting to use this. And most importantly remember that this is not a fertilizers . It's only a CO2 promoter.

Many people have doubts on the usage of this product so let me explain. This is a liquid CO2 and is useful for people who do not have pressurized or DIY CO2 injecting system in their planted tank. I used it alongside a pressurised CO2, and it gives decent results. However, please be careful as it also prompted Algae growth. Make sure you have some decent algae eaters in your tank before starting to use this. And most importantly remember that this is not a fertilizers . It's only a CO2 promoter.

### ⭐⭐⭐⭐⭐ Great with planted aquarium
*by A***E on 30 June 2020*

Very Good, I noticed plant leaves becomes little large n healthy with bright green colour within1 week. Mine is only fully planted aquarium with ferts n non - CO2 tank, but plants like vallisneria were brown n lack of new leaf growth. Now with Seachem Excel addition, vallisneria is growing new 2 leaves quickly. Even cabomba is v bright green n spread fronds very well. Floating plants like fern n water lettuce multiples so fast. I have to remove excess of them. Happy with the purchase.
