JBL PhosEx Rapid is a phosphate remover for freshwater aquariums and pond water to suit both fish and plants. This product reliably binds phosphate and thus prevents unwanted algae growth. Also suitable for turtle and shrimp tanks. How it works: a liquid iron compound reliably and permanently binds the phosphate dissolved in the water. Its effectiveness is shown by a brownish clouding, which disappears after 2-24 h.
To use: 10 ml/40 l water for >2.4 mg/l phosphate. Example: 60 l aquarium: 15 ml. For > 1.2 mg/l 10 ml/80 l and for > 0.6 ml/l 10 ml/160 l
