Good way to keep water butt in use and reasonably clean.

This product is a little pricey although it has kept my water butt free of diseases, algae and other contaminating organisms. It seems to do the job very well and I would recommend it to anyone who has a water butt.

I bought this product to put into a large water feature, as there was nothing else suitable at the time. It works very well concidering that the feature is in the sunlight most of the day. The only downside is that treatment is more often than I expected, but overall a very good buy.
