All Clear Algae Control
Prevent algae growth in your pond with All Clear
Thread algae develop when the aquatic plants fail to decompose the food supply adequately. Thread algae thrive in conditions with a high pH value and a low KH value. All Clear quickly removes troublesome slime algae and thread algae and hinders the growth of new algae. It is environment-friendly and is harmless to plants and animals. 250 ml is sufficient for 2,500 litres of water.
