"Excellent product!" star star star star star Put one in each of our small tanks, not really expecting much. But the water is sparkling less than one week later! Awesome product!
"Excellent results, very impressed" star star star star star This review is for an older version of this product Bought this for my water butt, the water has definitely become cleaner and the odour has now gone. Also those annoying gnats and flies are no longer present.
"Clean water butts at last" star star star star star I am so pleased with these wonderful discs that keep my water butts' water super-clean. No smell or dirty brown water since. I've been using them for two years and just one per large butt does the trick, and have just bought another two for my other butts. They really work!
"Brilliant - definitely worked for me!" star star star star star Our bird bath was constantly green with algae in spite of being regularly cleaned. When I received this little disk I gave the bath a very thorough cleaning and popped it into the water. It's light weight and shiny so I placed some decorative stones over it to keep it from blowing away and to deter the magpies. Eureka, it's now been in place for more than two weeks and the water has stayed clean. I'm delighted (as are the birds) and will be buying more to go in two small water features I have indoors.
"superb results - highly recommended" star star star star star This has cleaned the water in my waterbutt in only 2 weeks and it has stayed clean and odour free. I would highly recommend this product. It does take about 2 weeks to clear the water but then it stays clear. Excellent!!!
