Nishikoi Blanc-Kit Excel Natural Pond Treatment for Blanket Weed - Treats 13,500 Litres of Pond Water

Great product does the job.

this is the only product that has worked for me, it not only clears blanket weed superbly and quickly but also clears green water. One can almost see it working immediately, and in a matter of a few days, even the greenest, choked and manky water is crystal clear. The koi and myself are most impressed!

Does not appear to work at all, nothing happened, no weed gone, more weed growing all the time.The pond is now covered again, this stuff is supposed to stop new weed growing and doesn't.

Easy to use and it does what it says on the box. Undoubtedly the best product of its kind that I have tried to date. It kills off existing blanket weed and slows down the growth of new weed. Without a cure for blanket weed available on the market then this is the next best thing.

Does exactly what it claims, unlike more "modern" and infinitley more expensive products supplied by our local pond "experts" Great delivery and service

This product worked well within 2 days, though the effect did not last as long as I had hoped. I would recommend it.

the stuff works that is why I have been using this over 3 yrs. Needs regular top up - especially every month in summer time.

Works Great
