Designed for freshwater aquariums with rooted plants, these fertilizer balls address the need to feed plants directly through the substrate. Placed beneath the plants, they release the elements needed for fast, dense growth.
Why it matters
- Placed in the substrate under the plants, so nutrients reach the root zone where they are taken up.
- Supplies the elements plants need for rapid and lush growth.
- Free of nitrates, phosphates and copper, so the composition is stated clearly on the product.
- Sold as a pack of 7 balls, weighing 0.1 kg in total.
