“My small 600L pond water was very green verging at times to black. I tried a few types of home made gravel/media filters pumped from my fountain,the pond cleared but soon turned green/black shortly after. After cleaning out my pond, having moved the fish, I refilled the pond with a mix of tap water and rain water. After a couple of days with a fountain aereating I replaced the fish. Within a week the pond water had turned green again so I bought a Hozelock 1760 EasyClear pump 3000L. Four days later the water is crystal clear. Easy to install, good length of heavy duty cable.”
