Blagdon Green Away Pond Water Treatment, Clears Green Water and Suspended Algae Particles, Natural, Plant Friendly, Safe for Fish, 250 ml, Treats 5,000 Litres of Water,package may vary

I’m a koi pond owner, and let me tell you, this product is an absolute game-changer! I used it in my pond, and in just a week or two, it transformed my murky, pea-soup water into something that could be mistaken for Evian – my koi must think they’re living in luxury! 😆 It works by clumping waste that would normally slip through the filtration system, making it much easier to clean up and significantly improving the water quality. It’s honestly brilliant, but here's the catch: After adding it to your pond, you'll need to clean your filter material after a day or two. Trust me, it’s worth the effort – your pond (and fish) will thank you for it. I have to say, the transformation was so impressive that I half expected my koi to start sipping from the pond like it was a bottle of spring water. Definitely worth every penny! One thing to note: After treatment, the water does go very murky at first, which is just the minute waste combining together. Don’t panic! Leave it until it clears up, then do your pond filter cleaning. Pros: ✅ Transforms murky water into clear, clean bliss ✅ Helps with waste filtration, keeping your pond sparkling ✅ Works quickly – watch your pond go from soup to spring water in no time Cons: ❌ The product doesn’t remove the waste entirely. If you don't clean it from your filters, it will just break down and go back into the pond. I’d recommend this to any pond owner who's tired of looking at green, murky water. It really does work like magic – just be ready to do a little extra cleaning! I’ve attached a video of when I added this to a holding tank so you can see the results for yourself. Ponds always seem to go green in the summer – it's like they have a mind of their own! Which reminds me, I better stock up on this stuff before my pond turns into a swamp again.

Very good and pleased with results

BRILLIANT, I had tryed so many things to clear my pond, but this does just as it states. I did one measure, waited three days and did another. My pond is crystal clear. The water before treatment was so green you couldn't see anything. Highly recommended. 😃

Hasn't made any difference to the green colour in my small pond after 4 days. Was difficult to get a fully accurate dose as the ball bearing mechanism in the bottle doesn't work (releases the liquid back into the main bottle). Will try again, but disappointed that the results suggested not achieved.

dropped some in this morning and by tea time there was a difference, do remember to mix into a bucket of pond water first in order to spread evenly around the pond no smell, easy to use, safe for the fish, helps clear the water

Hopeless didn't work

Amazing! Works really well, pond water is now crystal clear. I’d not been able to see any fish before.

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.....

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.

But had to use more than the required amount

This product did not work in my pond.

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

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.
