If you have trouble with blanket weed then use this, It works great but do follow the instructions to get rid of it and if it doesn't completely get rid of it first time, Then continue with a second dose believe me it does work it certainly got rid of 99% of it with just one treatment, But i only have a smallish size pond about 7.5 feet by 6.5 feet and 22 inches deep you might need to use more if it's bigger than that. good luck.

I put two sachets in, then 2 more after 6 days and again after 7 days. Should need a little over one. Absolutely no effect apart from cloudy water the day after application. 2 more tomorrow but I have no hope of success.

After putting the first sachet in the pond I noticed the blanket weed was turning black ( dying ). Three weeks have past and I have put one sachet in the pond every week and the pond is free of blanket weed. I will continue with the product for a ten week course as directed. Great product!.

If this works I'll be so pleased. No messy mixing just throw the little packet in the pond. I can see my fish, which for a starter is very good. If it keeps working I'll buy more. This is the first week - so time will tell.
