A superior aquarium plant fertilizer in tablet form.


  • Promotes lush growth of aquarium plants
  • Contains Iron.  Develop strong roots

Follow API Easy Care Guide and use ROOT TABS when:

  • Properly caring for aquarium plants 

Without proper fertilization, aquarium plants gradually yellow, drop their leaves and die.  Aquarium plants require essential nutrients for vibrant growth.  API® ROOT TABS are formulated to supply key nutrients, including iron and potassium and carbon, to help new aquatic plants get off to a vigorous start and to keep established plants flourishing.  These nutrients are consumed over time in the aquarium and must be replenished for plants to thrive.  Safe for use with tropical fish.   

Add 1 tablet for each 30 square inches (194 sq. cm) of gravel surface.  Push midway into gravel bed.  (A standard 10 U.S. gallon [39 L] of aquarium requires 6 tablets.)  Add new tablets monthly for optimum growth.
