Dennerle Deponit NutriBalls are the universal nutrient recharge for all aquarium plants that take in their nutrients through their roots. They give new plants a boost to get them started and older plants a new burst of growing power. Simply push 1-4 balls depending on the size of the plant into the area around the roots and replenish every 6 - 12 months. Ideal for new plants and for complementary fertilisation - contains iron and important trace elements to boost growth from the roots up.
The more healthy the plants, the more efficient they are at using excess nutrients in the aquarium and competing with algae: healthy plants = no algae! There are no nitrates or phosphates in Deponit NutriBalls so they do not cause algae growth. Completely safe for your shrimp and snails.
Dose: 11-4 balls per plant every 6-12 months.
