JBL PhosEx Rapid 250 ml

Key Features:
• For pond water to suit both fish and plants: reliably binds phosphate and thus prevents unwanted algae growth. For freshwater aquariums and turtle and shrimp tanks.
• Immediate action: liquid iron preparation to reduce high phosphate values.
• Removes phosphate. Prevents algae growth. Clears cloudy aquarium water.
• 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 hours.
