A superior plant fertiliser that can be used for your plant aquariums! Without proper fertiliser, aquarium plants tend to gradually yellow, and eventually die. I have been using these for years and found these are the best to make my aquarium flourish with beautiful and healthy plants.
Each tablet lasts for about 6 months before they need to be applied again.

• 100% safe for fish (and even shrimp!)
• Encourages accelerated growth of aquarium plants when they need them most
• Promotes green and lush looking plants
• Accelerates root growth
• I recommend one tablet for every 5-10cm (be sure to plant deep where the roots are so tablets don't float)
• Reapply after approximately 6 months (depends on many factors though such as water change frequency, amount of plants in the aquarium, temperature, lighting, etc.
• Safe controlled release of essential nutrients and trace elements
• Add some lighting and watch your aquarium bloom!

*not recommended for tanks with fish that dig or sift through gravel
