A note on herons, we moved in on their land and bulldozed their ecosystem. If we build wildlife ponds, we should expect wildlife to visit them, including herons. My suggestion is to build a deeper pond so fish can swing lower and hide from herons, or, stock the pond with fish for the herons to eat. We want resilient, biodiverse ecosystems, not pretty water features for humans to hoard more and more of the natural world for ourselves.

haha, glad to see the pond has a net... fish safe from the birds.. good job..

Nice video bro, really helpful for koi keepers.

Very informative video! Loved it. Thanks a lot and keep it up mate!

Very helpful, thank you! This will be the first winter for our fish.

Love this idea! I think different depths would be great.

Nice easy to understand video, thank you

Can't wait to see it!

You didn't talk about how to cook and eat them.

My gold fish and my koi don't eat duckweed at all.

Is this available in the Untied States?

Thanks so much 😊

I would like to thank you for this advice to clear green water pond. I have experimented the product outside the pond in few glass jars and I found out that the products it does work. Later I used the products in the pond and really start to work and after five days the pond’s water for the first time become crystals clear. Thank you

It’s an Ad but well made informative ad. I understand barley straw works only with ponds where pH < 7.

You have a beautiful garden. Which place? My pond is super green after I planted water lilies 😢

Is a filter system a must have?

One question for you are fish getting less hardy what I ask this is when I was a young lad my dad had a pond and we had freezing weather for about 8 weeks even the sea on the beaches froze we could walk on the local Broad we had about 8 inches of ice on our pond and in the spring when it had all melted we didn’t lose any of the fish

Ash, your videos are always helpful…keep them coming ❤

Another great video, thanks guys!😄

Tap safe, a teaspoon would do this size pond.

Any carp woll eat this

Are Golden Rudd hard to keep?

At 8:50, Ash mentions waiting 24 hours between using Algae Klear Xtra and Pond Klear. Apologies for the confusion, but in fact we would recommend waiting a few days between these applications rather than 24 hours! If you are using both of these products and are unsure about anything feel free to email us info@envii.co.uk or comment below and we can clarify.

Feed it to your chickens

Should I move the fishes out of the pond before I put it into the pond?

Guys the pond in my girlfriends parents garden probably about 5-6 times the size of this will this product clear the 2 ft of silt and sludge at the bottom of the pond and kill the duck weed ??

Envii videos are great! So helpful ❤

All Envii videos are brilliant! So helpful ❤

HI. I'm a complete newbie to ponds. My pond has gone green and no matter what I have tried, it still goes green. I've lived here for 6 years and this has only started in the last year (at most). There's no fish in it anymore a heron took them, there are plants in there, and a waterfall. I have put a new UV bulb in, and emptied the pond, washed it out (took forever doing this) and filled up with mostly rain water. There's no overhanging trees etc. I have looked into using the pond clear but how often would I need to put it in? Its not a massive pond, about 3000 litres ?Any advice would be greatly appreciated, thank you.

A lot of rain in a short period of time can lead to a pH crash, especially if the rain is more acidic than usual. Test your pH using pond test strips or use Pond Equaliser to keep your pH safe and stable. Find out more here: www.envii.co.uk/pond-blog-post/pond-ph-crash

chemical name plz?

Thank you for this video…..it’s so helpful and I am dealing with this exact issue. I’m off to clean my pond ..👍

Very impressive video. But I would like to ask what are the steps to setting up a duckweed farm? Does duckweed require any amount of manure? If yes then what is the best type of manure to be used? Tnx

I was just about to toss out the insane amount of duckweed in my tank, I open youtube, and this is the first thing I see. 😭 Im so tired of maintaining ny floating plants

If it sinks the sludge to the bottom, how's my pump supposed to get it out

Eatable by people?

My goldies love em, my issue is they eat it too quick.

5 weeks in to a new pond. Had ammonia spike and now nitrite. And a load of sting algae. Just treated it today with your algae klear today. Just hoping the nitrites lower soon

#GrandpaPozo I'm more than grateful for your help my husband is back to me now after months of separation thanks to you sir

My pond is an acre do you sell bulk?

Also adding that an episod of rain will tend to fertilize your pond, as drops of water gets nitrogen and phosphate from the atmosphere and that is what essentially helps fertilize soils, turning anything green in your pond, but again as this video points out, Bacteria is key to getting rid of it.

For more about duckweed, check out our Complete Guide to Duckweed here: ruclips.net/video/OefaVDLD028/видео.html

The water under the duckweed is darker suppressing algae growth and the cooler water has more dissolved oxygen. Ideally there are floating or emergent plants with roots absorbing nutrients and surface or emergent leaves blocking light. A layer of algae on submerged rocks is helpful in absorbing nutrients to compete with water suspended algae. Having some exposed agitated water allows for oxygen to enter the water and carbon dioxide to leave. If you remove all the duckweed at once any single cell or colonial free floating algae in the water will suddenly take over as an algae bloom with the increased sunlight and lack of nutrient competition. At night they will use so much oxygen they will make the fish suffer hypoxia. After producing carbon dioxide all night it reacts with the water and makes carbonic acid and lowers the pH so fast if there is no buffer in the water and the fish with hypoxia suddenly suffer from acidosis. This injures the one or two layers of epithelial cells covering their gill capillaries. With injured gills they can not release CO2 and ammonia in the presence of low oxygen and suffer slowly or die.

How do you maintain water levels during heavy rain?

Or.... hear me out, put fish in there and you don't have to feed them!

And then you dry it out and use it the next time you want to feed ducks.

4:40 not sure where this sentiment comes from. I have big koi and tons of plants, you just gotta pick the right ones, not the ones like hornwort which they eat. Lilies and any kind of reed-like plants will do fantastic with koi. Its also fun to watch the koi look for food in between the plants

But how do I get rid of it

Thanks for this!😊
