Review: This product is amazing, had pond full of blanket weed and now ... - This product is amazing, had pond full of blanket weed and now none. As long as you use Envii Pond Equaliser first and follow the instructions to the letter in 3 days the weed was gone. Dead weed did block the pump but i can live with cleaning that out so i could get rid of that horrible weed. Instructions also sent by email and if you have any questions the seller is always at the end of the phone. Would recommend this product and company.
Review: It works! - Envii produce a range of products for pond maintenance and health - so many that it is quite bewildering. There is a different one for every type and depth of pond algae and any adverse condition your pond might face it seems. On this particular one the 'Blanketweed Klear' there is a lot of small print and instructions to follow. You feel like you have to be some sort of amateur botanist to grasp it all. I only have a small wildlife pond and I didn't really anticipate that degree of complexity. The company even emails you with yet more information and instructions after you purchase on desertcart - a unique experience for me. They are especially careful to point out that this product only works on surface blanketweed and that it may not work at all if your pond water isn't at the correct pH, for which they advise you purchase another of their products! Now, is this just outstanding customer service, or a hard sell to make you buy more of their stuff? I suppose if you own a prize Coy pond you might want to follow their instructions to the letter. Personally, I couldn't be bothered with all the extra fuss and expense, so I went ahead and used it anyway - it seemed to work, regardless. The powder is sprinkled on the surface weed and after 1-2 days it all congeals and you are able to rake it off. It also seemed to bring up a lot of algae from the depths too. After raking off the congealed weed you then add a tablet (also provided in the pack) dissolved in water, to clear the murkiness left behind. This worked too! Pond plants were left unharmed.

## Questions & Answers

**Q: I have blanketweed strangling my floating starwort and watercress in my wildlife pond. It’s wrapped around it under the surface. How would I use it?**
A: Honestly I would not buy this product, it turned my water a horrible brown colour (from crystal clear) overnight and its taken well over a year to get my water back clear again. I recently joined a pond group on fb, and was recommended 'Cloverleaf:Blanket Answer'...it's a similar powder treatment, I used a toilet brush to scoop out all the blanketweed I could and then used the treatment as per instructions..Good luck 🤞

**Q: Is this ok for Sturgeon**
A: It was fine for Koi not sure for Sturgeon. Check with manufacturer.

**Q: My pond is full of blanket weed but not on the surface - is this ok to  use?**
A: HI 
Our pond also has blanket weed around the edges and we have been using it to clear it away. seems to be working but it does take time.

**Q: does this remove phosphate?**
A: Do not know and it does not remove blanket weed

### ⭐⭐⭐⭐⭐ Seems to be working
*by J***B on 24 April 2025*

Having replaced a leaky small pond with a new one over the winter I filled it with rainwater before replacing some of the plants that I'd saved from the old pond. With a pump circulating the water to aerate the pond and some oxygenating plants I expected the pond to be healthy and clear so was alarmed to find vigorous growth of blanket weed infesting the pond. Attempts to reduce this by trying to fish it out proved futile so I decided to try this powder. Having sprinkled the powder over the surface weed with the handy scoop included in the pack, I left it for 24 hours and then fished out the browned weed carefully checking it for any signs of wildlife. The pack also contains two tablets which are designed to help prevent regrowth of the weed. Each tablet treats 5000 litres so I had to estimate the amount to put in my small 600 litre pond but this was easily done by crumbling to tablet into a powder. So far the pond is clear with no signs of blanket weed regrowth so the product seems to be working as advertised. 🤞🤞
