JBL the 7 Balls are a long term fertiliser, which will provide all of the nutrients your planted aquarium needs for lush growth.
Iron especially, is vital for healthy plant development, and these nutrient packed spheres will deliver it straight from the roots. They also contain the trace elements that all plants require. The nutrients are released slowly over a long period, to ensure the best results.
This type of supplement is ideal for plants such as echinodori or cryptocory-nae that absorb sustenance via the roots. As the balls do not contain any nitrates or phosphates, this lessens the chance of an algae problem.
The 7 Balls are best for an established tank, for a new aquarium try Ferropol to boost iron and all other trace elements.
