JBL 7+13 Fertiliser Balls

JBL's 7+13 Fertiliser Balls are a direct to root plant fertiliser product, providing nutrients for up to a year! 

Place one or more of the fertiliser balls under the substrate of your aquarium, close to the root zone once a year for slow release of essential nutrients and trace elements. 

This product promotes optimal plant growth and overall health, which in turn reduces the amount of algae growth in your aquarium. 

One pack contains 20 fertiliser balls.
