Instructions for using Multi Bottom:
1. Place one stick for every 15x15cm (~6x6in). 8 Sticks are used in a standard 60cm (24 in) aquarium on average.
2. Insert sticks 2-3cm (0.75-1.15in) from aquatic plant roots, placing the sticks as deep as you can into the substrate (Bottom Release is recommended as an easy tool to place Multi Bottom into the substrate)
3. Nutrient content of the sticks last for 2-4 months. When you place a new Multi Bottom, place them away from where the original was, as there may be residual nutrients in the substrate from the old stick.
