Comprehensive supplement for the planted aquarium

Provides micro elements, trace elements and other nutrients

Does not contain significant levels of nitrogen or phosphorus

To understand what Seachem Flourish does it is best to understand what Macro and Micro elements are :

Macro Elements consist of elements in large supply

Micro Elements are usually only needed in a trace amount

Seachem Flourish is a base line plant supplement which is also safe for aquariums with shrimps in it . Seachem flourish contains a great assortment of micro elements , trace elements and other basic plant nutrients , including calcium , magnesium , iron etc 

For macro element (NPK) fertilization, use Flourish Nitrogen™, Flourish Phosphorus™ or Flourish Potassium™ as needed. Flourish® is safe for invertebrates such as shrimp.

Flourish® is designed to be used with other macro and micro-nutrient supplements. Other manufacturers try to include ALL necessary nutrients, leading to overdoses of micro-nutrients in an attempt to raise macro-nutrient levels.

So basically , you can use Seachem Flourish as a base line but then you simply add whatever Macro element your planted aquarium is short of to ensure your plants are strong and healthy

Use 1 capful (5 mL) for each 250 L once or twice a week. For smaller doses, please note that each cap thread is approximately 1 mL. Refrigeration is recommended 3 months after opening. [/expand]
