Blagdon Clear Pond Water Treatment, 1 Litre, Clears Dirty Green or Brown Cloudy Water Quickly, Natural, Wildlife Safe, Harmless to Fish and Filter Bacteria, 1L, Treats 20,000 Litres of Water

I have a new wildlife pond that does not have any kind of pump or filter. After a few weeks the water was very murky brown and I couldn't really see the bottom. I found the product easy to use. I followed carefully the clear instructions for calculating the volume of water in the pond and therefore how much of the product I needed to apply. The water volume calculation could only be an estimate during to the irregular shape and depth of the pond, so if anything I decided to slightly underestimate the amount of product to apply. I mixed it with warm water in a bucket and decanted the mixture into a watering can fitted with a rose, then poured the mixture evenly over the pond surface. The water cleared gradually day by day until after a week it was as clear as could be expected. Now I can see everything at the bottom of the pond, so the product has been very effective, even during extremely hot weather. There is plenty left for any further dosage so I think it's good value for money .

Use this most of the time along with barley straw in my pound works well. I also use in my aquarium but have to get the right dosage exactly or will kill fish, find its much better to use than most of the proper aquarium cleaners which are no good and way over priced will cloud up but that shows it's working within 24hrs water is really really clean when you empty filters use will see results for yourself but as said Got to get dosage right, I have a 200lt best if you know your literage in tank then you get the dosage right, if not have to do by size and that is harder to work out i did get it wrong at first now I don't and a bottle last a long time than others.

Worked a treat for my container pond, which had murky water due to the unwashed stones we’d added. The dose was easy to calculate and I sprinkled the solution over the pond surface using a watering can. Left it overnight and the pond water is so clear I can see right to the bottom now.

Made no difference to the colour of my pond water. Gave 3 doses over 6 days, no change.

A good solid product from a reputable brand . It does the job !

Great stuff works a dream and good value

This was an expensive item so thought it would do the job. This has not helped my murky pond at all, in fact it has made it worse. I followed the instructions to the letter. Would not recommend.

Need to know pond litres accurately

No fue muy buena compra, no se si por no saber exactamente cuanta cantidad poner al estanke tengo o si tenia espectativas mayores que no cumplio, tuve que utilizar otro producto para conseguir algun resultado y ver el agua clara, seguramente agruparia las particulas y realizó su funcion, pero yo esperaba fuera otra su funció, fuera UTIL limpiando el alga,,,

The product itself is good! But I have ordered the Blagdon Green Away twice, and the seller has replaced my order with the Clear Pond, with no explanation. Guess I can't trust the seller! Beware.

Dieses Produkt hatte Null Wirkung ,das Wasser ist genau so trüb geblieben wie vorher.Außerdem wäre eine deutsche Gebrauchsanweisung,wie man bei anderen Artikeln kennt empfehlenswert.

2 traitements et aucune amélioration ! C'est agaçant toutes ces belles promesses n'ont tenu. Encore de l'argent jeté par les fenêtres.
