I popped one these in my algae prone garden fountain after a good cleaning and, after several weeks of hot weather, no algae! Normally the fountain would be trailing big streamers and the filter would need cleaning. I don't understand te mechanism involved, but results are good so far.

Clears out pond from algae in about 2 weeks. So much better/cheaper than using chemicals!

I use these every year. Two bales keep my 2200 gallon koi pond clear all season, without using chemicals, I have never had any ill effects on fish or plants and would recommend them for anyone with small to medium sized ponds.
