## Description

Product description               CARBON PRODUCTION: All plants require a source of carbon, and Flourish Excel is a great and convenient source of bioavailable organic carbon. IRON PRODUCTION: Flourish Excel also possesses iron reducing properties, thus promoting the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). PHOTOSYNTHESIS: Plants must produce longer chain carbon compounds (photosynthetic intermediates). By dosing with Flourish Excel you bypass the involvement of chain carbon compounds and introduce the already finished, structurally similar compounds. TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL. SAFETY: Flourish Excel is completely safe for fish, however, if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.                  Directions               On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 US gallons). Thereafter use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL. It is recommended to use it every other day rather than daily if you have Anacharis in an aquarium.

    Removes black algae from aquarium
  

*by M***N on Reviewed in the United Kingdom on 31 August 2024*

We got this to address black algae that must have come in with fish or plants and was taking over our aquarium. Took a few months of daily additions but finally got rid of it. Now just add when we’re doing the water change.

### ⭐⭐⭐⭐⭐ 







  
  
    Awesome Poduct
  

*by I***K on Reviewed in Canada on 2 July 2023*

The product is awesome for aquariums with plants. Helps with color of red plants. Bonus is if used every second day 1 cap for every 30 gallons it prevents slime algae and DOESN'T kill shrim

Had an outbreak of Blackbeard algae. Researched it and found that this is good for the plants and kills that stuff. The algae turned red and died. My plants are flourishing. Delivery was quick.
