Blagdon Green Away Pond Water Treatment, Clears Green Water and Suspended Algae Particles, Natural, Plant Friendly, Safe for Fish, 1 Litre, Treats 20,000 Litres of Water

Did the job after using I waited several day as instructed, the water is now much clearer and the fish look healthy, good easy to use product.Elaine

That my pond was like pea soup after a hot April/May is an understatement, I couldn't see an inch into the pond and wasn't even sure the fish had survived the winter.....my Blagdon 6 in 1 pump wasn't up to the job, partly because the UV bulb had failed, as did the new replacement bulb, so I bought a second 6 in 1 pump, put some Barley straw in and still no effect even though I was cleaning the pumps weekly.... time to try Greenaway.Pros - Almost immediately it turned some of the algae brown, within 4 hours I could see a couple of inches into the pond and spotted a couple of fish.....24 hours later and I could see at least 4 inches into my pond and some of the underwater bridges I had with plants on, the fish are so much happier and darting all over the place even though the clarity isn't brilliant yet, at least I know they are alive!Cons - I used the water from my water butts in a watering can with a rose on to spread the product all over my pond, from the pictures you will see that it has turned the powder coating on my ironwork pond covers reddish/brown, I also have some red spots where it has come into contact with the slabs on the edging, if I need to use it again I will be careful how I put it in the pond.I am cleaning both pumps out once a day until the water clears as even in 24 hours the amount of green sludge in the pumps is horrendous.I am confident that with patience this is going to work, I'm not going to rush giving it a second dose as already my fish are much happier, more active and at least I can see them..... I will update in a week or so.....

We have used this product before, but purchased from a garden centre.I have always found treatment of green water a dark art! what seems to work one year or with one type of green water doesn't the next time! However, whenever we have experieinced problems with the treatment we have always discovered that the problem we faced was not what we thought it was. In this product's case, we know that our pond will be subjected to at least 5 hours of direct sunlight through the months of May through to the end of September and we nearly always experience an algal bloom of some type or other and this seems to sort it out.Best applied first thing in the morning (ph is often lower then) and if you want the maximum benefit test the ph of the water first as this product is most effective between a ph of 6.5 to 8.5. Mix the required amount into a watering can and sprinkle it over the surface of the water you want to treat. It should clear the water in a single treatment, however, a further treatment may be required. You should expect an increase of sludge from the dead algae which might require a filter and pump clean in heavily "infected" ponds and I always use Blagdon sludge buster after applying this product to break down the dead algae to prevent that being a problem.Better used as soon as a bloom starts to form, or as we do around once a month from the end of May.

Dud not work as well as I expected. Still need to clean filter and pump weekly.

Works like a charm - had to give three treatments in our new small wildlife pond as it was completely green - but now it is completely clear. Luckily three treatments were in the bottle so only needed one. It took me a quite a few seconds to figure out how to refill the top part! If you tip it upside down, it does not refill it - you just have to gently squeeze the bottom of the bottle. Ingenious design, as it only dispenses the amount you squeeze into it. Would buy again.

Does absolutely nothing - avoid.

Straight forward and simple product to apply to the fish pond ,not harmful to plants

Great value for money

Este producto es mágico. He probado muchos productos ingleses para tratar de evitar que el agua de mi estanque se ponga verde. Este es el único que me ha funcionado a la primera. He vuelto a comprar otro para tenerlo de reserva.

Da quando uso presto prodotto (4 anni) ho sempre un'acqua limpida e soprattutto non crescono alghe.

Es eficaz pero no duradero.su efecto comienza a las 24h de usalo, pero pasado unos5dias hay que volver a empezar

But had to use more than the required amount

Ho inserito il prodotto nel laghetto con le dosi indicate a distanza di una settimana perché le alghe non andavano via, alla fine la situazione è rimasta uguale se non peggiorata.
