Essential Nutrient Boost These aquarium root fertilizer tablets are packed with nitrogen, phosphorus, and potassium, ideal for promoting the growth of lush crypts, majestic sword plants, and delicate carpeting plants.
Slow-Release Formula Designed to dissolve gradually, the FZONE all-in-one root fertilizer tablets provide a 2-4 months supply of nutrients, allowing roots to naturally access the tabs. This prevents sudden changes in water chemistry and reduces the risk of overfeeding.
Beginner-friendly Unlike other aquarium fertilizers, this compressed root fertilizer requires no additional preparation or dissolution, saving you time and effort. It's perfect for busy aquarium enthusiasts and beginners alike. The compact packaging makes storage easy and helps keep your aquarium neat.
Simple Application The tabs are easy to use and always sink. Each root fertilizer tab weighs about 0.6g and can cover a 5-6 inch area. Just bury them about an inch into the substrate, sit back, and watch your plants come to life. You'll see noticeable improvements in plant health and vibrancy.
