Packed with slow-release Nitrogen, Potassium, Phosphorous, and trace elements, it’s a root-loving powerhouse for heavy feeders. Its chunky 6-8mm grains boost water flow and oxygen, encouraging beneficial bacteria and making your plants thrive. Conveniently pre-bagged in mesh for easy handling, just pop the whole bag in! Stack it up to shape slopes in your aquascape. Nutrients last about three months. Pair it with UNS Controsoil or Controsand on top, and remember: no washing needed! Just spread under at least 2 inches of substrate, and watch your underwater garden grow.
