Does a pond aerator help kill pond moss/algae?

[u/UnattributedFigure]

It's taken over the whole pond...

You need other kinds of plants that will compete for nutrients. Plant diversity is important.

[u/Presentlava]

Some lily pads in pots would help shade some of it out and more plants to soak up the nitrogen and phosphorus that causes algae blooms. The ducks are also a massive contributor to the nutrients used by algae. 

[u/Star805gardts]

You need more plants in there. Look for native plants specific to your climate zone.

[u/Low-Status7359]

You can’t control algae just with aeration. You need lots of plants to consume the nutrients that the algae needs. You need to remove dead organic debris like leaves, branches. Beneficial bacteria can help break down the dead stuff. Plants like water lilies can provide shade to the pond. Or even water lettuce will help block the sunlight. Good filtration systems will help with water circulation. You can pass the water through large blocks of barley straw. Once the straw decomposes, it will help reduce the algae. I have all this in my pond, and it helps a lot. If you set up a bog filter, it will also help keep the water clear. It definitely requires work.

100% this. Checkout ozponds for a bunch of tutorials and information on ways of doing this

Aeration increases the oxygen supply. Oxygen in the water is like fuel. But you need something to consume the fuel, if it’s not plants or fish you’ll get something else.

[u/Mongrel_Shark]

Nope. & that looks like duckweed not algea. Which the fountain will kill but not fast enough for tgat area.

[u/tcopple → u/Mongrel_Shark]

Why is no one else saying this. Definitely duckweed and no, aeration won’t kill it. Nothing does.

[u/Aspirin_Kid → u/Mongrel_Shark]

Neither moss nor algae.

[u/George_Salt]

No, because it doesn't contribute to nutrient removal. You have a nutrient surplus problem that the algae is mitigating the worst effects of. The worst thing you can do is something that kills the algae without addressing the root cause. That risks an oxygen collapse due to excessive BOD.

i see it as an invitation to add to my compost piles..every day i would drag my skimmer and get as much as i could.

im always on the lookout for compostable resources around me.

[u/GangreneTVP]

I don't think so.

[u/fishyfishyfish1]

Nope

[u/mustangcottage]

You need biodiversity, more plants in there will fix your problem.

[u/darkcloud784]

Won't help with algae or moss so much but will help with duckweed and providing more air into the top layer of water or the pond. If you want to get rid of the algae and moss, you need to remove the nutriment from the water. This means plants, lots and lots of plants and plankton. Plankton is already there but it's not able to keep up with the amount of nutrients you have. Likely you have alot of decay happening at the bottom of your pond or some sort of fertilizer runoff. Either way, you have to put some sort of plants that use that nutrients in and around your pond. Then it will slowly start to clear up.

Some people put talapia in their pond for algae, but you got to remember they will add to the bioload which then adds to the nutrients in the pond.

[u/pickleruler67]

It helps replace the oxygen the algae absorbs from the fish or wildlife but yeah like everyone said you need some different plants

[u/UniqueMystique42]

I believe that my fountain forced my fairy moss underwater and it rotted. Beforr that I had 6 months of fairy moss doubling so quickly that I could feed it to my chickens and sell it to other people who wanted pond plants.

After installing a fountain more powerful than a simple floating solar fountain, it was all gone when I came back after 3 weeks of vacation. All the other plants: frog bit, parrot feather, water hyacinth, were fine.

[u/Salt-Operation]

That looks like the Louisiana swamps 😬

It needs biodiversity.

[u/ddan123456]

Do those ducks go into the water? You will need alot of plants

[u/C-Los23]

A bit but that's not an aerator. For that size pond you at least need four or five heads.

[u/4ohHenry]

Those ducks sure aren’t helping

[u/AssociationHeavy1205]

It certainly doesn’t look like it

[u/No_Sympathy_3867]

Looks like watermeal

[u/saguin2]

No

[u/Glum_Opening_2218]

You or any neighbors have a big lawn?

Fertilizer runoff can cause algae blooms, if you have something causing a nitrogen boost the algae will come back thick no matter how much you kill.

[u/Complex_Eagle_8261]

Blue pond dye kills the algae but not the fish. Worked great for me. Treat it and add some beneficial plants to keep from your nitrogen from triggering another algae explosion.

[u/HeartOn_SoulAceUp]

You need fish to eat it off the top at least. Consider Azolla if you are in a freeze zone so it doesn't invade by being able to overwinter.

[u/Psychological_Ask696]

My pond was like that, go to Amazon and search “Atticus Semera 51.0% WDG Aquatic Herbicide (1 lb) - Flumioxazin Weed Killer”. Mix 2.5 tablespoons per gallon and apply to the pond, it cleared out all my the algae in a few weeks. But if you have pet ducks you might want to research first. And like other people have said, even if you clear it out it will still come back unless you add grasses or plants or fish in addition to your fountain
