Everything needed for aquarium fertilizer
The jars are airtight, fertilizer are easy to mix and the micro took over night to dissolve but macro dissolved immediately. The 2 dispenser that come with it has two caps. One to add fertilizer and water to mix and other to bring out small amount of fertilizer so that you can use the pipette to get desired amount of fertilizer without spilling anything or contaminating anything. There is also 2 pipette included that they do not mention. Overall great experience. Plants love it. More vibrant plant.
