My pond is green

[Derrick]

Well my uv is priceless. Never heard of algae mutation. Never had a prob since I got the light & filter

I had the UV light in my pond, I had lots of algae in my pond, I used to use a rake to haul it out, I tied putting it in a composter, the dam stuff doesn’t even rot, in the end I let it dry out and burnt it

So much bad information being shared here. Filtration is of course necessary - UV is not. First you said sunlight grows algae; then you mentioned 100 degree temps. Which is it? I have both sunlight AND high heat in summer, don't use a UV and my pond is not green. I have lots of plants and I can STILL see my fish. So what's the difference?

UV is only useful for single celled floating algae. And I use the term "useful" lightly. It will kill it, but then you're left with a pond full of dead algae, which only feeds more algae.

Reduce the nutrient load in your pond; more plants, fewer fish, feed less, grow more bacteria, remove rotting organic material. It's the only way to KEEP algae from becoming an issue.

I have a pond, 6 feet long, 3 feet wide, 4 feet deep

It has a waterfall with sponge filters in it, fed by a pump, no fish, no plants yet

The water has gone green like pea soup

The pond is sterile, even the snails died, there are no frogs, newts, just a lot of bugs that I think are shrimp something like them

I have put in barley straw bundles in the hope they will clear this green water

I have been told to try this Walsted method

I’ve never heard of it

My pond was filled over a month ago now, probably longer

All I want is a clear pond to put fish in it

I am open to all suggestions

I haven’t put a net over it yet, no fish in there for the herons, but he does hang around

I tried uv lighting filter and pumped filter just like you and the only way that has worked really well is a pea shingle little pond at the top of my water race with plants in (iris etc). Plants thrive in pea shingle and water is crystal clear.once a year I clear the shingle/plants of waste (rinse) and the fish have gone from for to twenty by themselves!? Mesh is essential as heron cleared pond twice .relocate frogspawn out of pond as it kills the fish!

My new pondwent like pea soup too ,filter with uv light did nothing as did the bale of barley straw, the assistant at a garden centre told me to make a pea shingle bed and water plants in it at the top of my cascade , the roots act as a filter ,it works for me very well! I have to reduce /clead the roots once twice a year and the water is really clear,so much so my local herons cleaned out the fish so now I fitted mesh to deter them -they still call to check!

I haved got swan musels in both of my ponds, it took a while, but the have cleaned up my pond wonderfully, I can se the bottom now and the fish
Chemicals never done anything
I now have floating plants in there, goldfish, Swan mussels
All the advice I was given here was no god to me, some was totaly rubbish, I'll listen to my koi breeder
Conversation on this thread is now finished
Thank you

Haha. Well good luck to you and your mussels.

I’d say the “took a while” portion of this outcome is what really worked. Time and patience are the two things new pond owners have to learn to apply to the pea soup equation. But that’s just more rubbish to smart folks like you.

 

[Derrick]

Well they worked a lot better than all the options I was given here
Yes it took a while, 2-3 weeks, chemicals never worked
The mussels did

Well, in at least one of your posts you mentioned using a UV light for algae you could rake out. String algae is unaffected by UV so in that case you miss applied the advice you were found or were given. Not a fair assessment. And in every case, you should be looking for the cause of the overgrowth of algae to find the solution. Lack of swan mussels was not the cause of the algae in your pond. Can you explain why you think that worked?

Having said that I’m happy for you. You found something that works and you’re enjoying your pond pond. That’s the whole point..
