Flourish Excel is a liquid carbon supplement for planted aquarium keepers who want to support plant growth with or without a CO2 system. It gives plants an available source of carbon in addition to, or instead of, dissolved carbon dioxide, which matters when gas injection is limited or unsuitable for a given setup.
Why it matters
- Plants can take up carbon from simple organic compounds, not only from CO2, so the product offers a second carbon route for photosynthesis.
- Its use is compatible with gaseous CO2 injection, and it can be given with or without gas dosing.
- Alternating it with CO2 injection is suited to tanks where adding gas may cause a sharp drop in pH.
- Its strong reducing properties convert iron toward Fe2+, a form plants absorb more readily than Fe3+.

What it works with
Flourish Excel is intended for planted freshwater aquariums, whether they run a CO2 system or not. It is designed to be used together with the standard plant fertiliser routine, and the alternating method is particularly relevant for setups where CO2 injection affects water chemistry.

Frequently asked questions
No. The product can be used with or without gaseous CO2, because plants can take up carbon from simple organic compounds as well as from CO2. Using it is beneficial whether or not your water is saturated with CO2.
You can combine them. Alternating between the product and CO2 works especially well when adding CO2 alone could cause a sharp drop in pH.
Yes. The product has strong reducing properties toward iron, increasing the amount of Fe2+ ions, which plants absorb more easily than Fe3+ ions.
It contains compounds structurally similar to photosynthesis intermediates, so plants receive these building blocks in a ready-to-use form and don't have to make them from CO2 first. The product does not contain the exact intermediates themselves.
This is a 250 ml bottle with a packaged weight of 0.25 kg. Its EAN code is 000116045605.
