Extract of Barley Straw 1 Litre

Wasn't sure what to expect from this product. Many people had recommended barley straw extract to combat problem of pond algae so i gave it a try and waited. And waited. And waited. Then i put some more in. And waited. And waited. What the heck, I put even more in (my pond is ca 2400l; by this stage id used half the bottle). Was about to tip the rest of the bottle in (it says you cant overdose!) when i noticed that although there was still a lot of green algae, it was now a an amorphous mass rather than long stringy filaments. These were quite easy to remove with a net and (touch wood), it seems to be doing it job and the problem is under control. So in summary, seems to work but takes much longer than you might expect. Happy to use again if/when the problem reoccurs.

Barley straw was recommended by a pond expert to remove blanket weed.Although it has reduced the problem the weed still exists and you need to keep on top of a regular dosage.The upshot is you need apply this product early in the springtime before the hot weather to be effective.

This is the first time i have used this so i will tell you more over the next few month on how it preforms

I bought this product to tackle blanket weed in a small pond and, combining application with physically removing the weed, it did eventually work and, adding a small amount each week is keeping it clear. I think having some oxygenating plants also helps.

I dont know if it has worked yet

Always use and pond stays clear all through the year

just OK

Great product, super service and even arrived a day earlier than expected. A big thank you.
