UNS Plant Food All In One Aquatic Plant Fertilizer

The two main ingredients for healthy plant growth are light and nutrients.  Adding fertilizers to your tank can promote healthier, faster growth.  After months of testing on our own tanks here at Buce Plant, we are proud to bring you Plant Food by Ultum Nature Systems. 

Plant Food is a comprehensive aquatic plant fertilizer which delivers all the micro and macro nutrients required by plants to grow.  The concept derives from "Estimative Index" or "E.I." dosing which aims to constantly supply your plants with all the essential nutrients required for growth.  Plant Food is designed to perform the same task while reducing dosing frequency from 6 times to 3 times a week. 

  • All-in-one fertilizer supplement for aquatic plants
  • Contains necessary micro and macro nutrients for healthy growth
  • 500ml bottle with pump top included
  • Extremely easy to use
  • 1 bottle treats 2500 gallons
  • Dose 1 Pump for every 10 Gallons / 1-3 times a week
  • 50% water change once a week is recommended

Pro Tip: If you have soft water or you're using RO/DI water, use a GH booster to ensure that magnesium and calcium levels are correct.

Dosage will vary based on the amount of plant mass and speed of growth in your tank. Faster growing and more nutrient demanding stem plants will require more frequent dosing compared to slow growers such as Bucephalandra, Anubias, Moss and Ferns.  Dosing 3 times a week is advised when adding CO2.  If you experience algae growth after using Plant Food, cut dosing to once a week.
