Legend C5 Eos™

Legend C5 Eos™ is a source of bioavailable organic carbon a powerful and efficient source, important for all aquarium plants. This is typically obtained from CO2, but, may also be derived from simple organic compounds (in the form of CO2 dissolved in the water) is one of the most important nutrients for optimal plant growth.

A shortage of carbon leads to the cessation of plant growth, while algae take over.

Regular addition of Legend C5 Eos™ provides strong and healthy plants so that the algae (brush and filamentous) disappear as a result of much better plant growth.

The assimilation of Legend C5 Eos™ by plants is very fast.

Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Legend C5 Eos™ 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.

Dosing Legend C5 Eos™ will boost your aquatic plants. They will start to grow and become stronger and colors will be more intense. They will be able to compete against algae making your tank look great. Combine this product with Legend Essential™ and Legend Heaven™ and you have got all the essentials for a healthy planted tank. There are more suitable solutions in the range of Legend ® fertilizers.
