envii Algae Klear Xtra – Blanket Weed Treatment for Ponds, Removes Blanket weed & String Algae Working All Year Round, Safe for all Fish & Plants – 500ml Treats 10,000 litres

The media could not be loaded. Brilliant results seen within 3 out of 7 days treatment. Water much clearer.Normally we would have had to clean water features out totally to get this result.So far so good!

It seems to be working. Much of the string algae has gone after a month. There is more treatment needed to completely eradicate the problem

After trying another brand which leaves the water a lovely blue green colour and claimed to clear blanket and green algae I needed something that actually works. I decided to give this one a go. Instructions say to dose once a week for three weeks. After the very first dose there was a marked reduction in blanket weed/string algae. Following the second dose there is very little blanket weed or algae visible. Very impressed.

I bought this item twice. It does clear the algae but not completely. Hence the algae re grows in a very short time. This makes it very expensive. Also the dispenser is defective. The green ball at the neck of the bottle was dislodged in both purchase making it impossible to measure the amount needed. Hence it is less convenient.

Easy to prepare. Too early to say how effective it is and second application still to be made. String algae appears to have slowed down.

Hi, what a waste of time, made no difference at all to my pond.. don’t waste your money on this product.

Its ok

Amazing - does exactly what it says. Got rid of pond weed and cleared up the water in two doses. Well worth the money. Doesn’t harm the fish or other pond plants.
