My rain barrels develop a strong odor and the water turns bad after several weeks sitting in the 100+ heat. After talking to the people at Gardners.com, they recommended that I try this product, but cut each packet into quarters (a more appropriate size for my 75-gal. barrels). I did that and put the packets in the already bad water, but it did nothing to clear it up. After some recent rains, the water did smell better, but I am guessing it is because most of the bad water was forced out by the new rain water. I am not pleased with this product, but I can't say it won't work if you put it in when your water is still good.
Bottom Line No, I would not recommend this to a friend
All gardeners want to be green — except when it comes to water. Whether you have a fountain, pond or a small reflecting pool, chances are good that at some point you'll have to deal with nuisance algae.
