- Green pond water is not bad for fish. It is actually making the water safer for the fish. The water goes green because there is not enough nitrifying bacteria in the pond.
This is easily fixed by adding more biological filtration (which provides more homes for the nitrifying bacteria) or adding more bacteria manually to the pond.
The best biological filter in my opinion is a bog filter. They can be easily made yourself nice and cheap. Best of all they are low maintenance and provide crystal, clear, fish safe water.
Here are some links to help you learn more about biological filtration and nitrifying bacteria.

My 25 gallon biofiltered pond is green. My fish look happy, i can't really see him unless he comes up, but he's happy. So seems to be fine like you said.
Thank you very much I thought I was doing something wrong with the green water and I got the master test kit amazing
Glad I could help 😊👍
6-12 months seems a long time to wait to see if the water will clear up.
I am glad that I have put in a bog filter during initial construction of my pond (still in progress).
Yeap. To be honest I’m a bit disappointed with this expensive pondkit (I will make a video once it’s a year old). You just can’t beat a bog filter! But even so I need to allow 12 months for the pond ecosystem to fully establish itself. If I still have issues then I will add a bog filter and fix. Thanks for watching all the way to the end.
I love your videos thank you
Glad you like them!
How does the pond look now after 4 months? Hey congrats on hitting 1000
Thanks mate. Looks great I do need to add a bit of flocculent every 2 months or so. But otherwise perfect. The goldfish eat any string algae.
Thanks
👍
Ahhhh! I just noticed you have nymphaea too! Mine are all dwarf forms. But it still looks good. Got 4 different colors. Pads are all just purple tho :/
Sounds cool.
thanks Sir
Anytime 👍
Do you ever find you have issues with birds getting your pond fish? I'm in west Gippy too and worry that the bright goldfish might be perfect dinner for our local heron and kookaburra
Not so far. The pond is very close to the house so lots of movement (people,the dog, and cats). I think that helps. I’ve had ducks come into my native pond. I have a few ibis that visit the pond down the back but I currently have no fish down there it’s more a retention pond. Once I get it cleaned up and filtering well I’ll add some southern Pygmy perch (cannibal creek strain) that way If they find their way into the local waterways I won’t feel bad.
Thank you very much can my koi survive the winter I live in Washington state we get maybe a week oor two of freezing weather
I’m not a koi expert, I’m not even allowed to keep them where I live. But they should be fine.
Hi wanted to know if the water is like pea soup will it affect the beneficial bacteria?
Green water won’t impact on the bacteria. It is a sign that there is not enough to process what is being produced. More surface area will create more bacteria.👍
Hey Kev, we have a 2 yr old pond and a bog filter. The bottom always looks dark and alot of muck. You can't see the fish very well. Any suggestions ??
Have you netted or vacuumed out the muck? That usually helps.
Hi Kev, is it generally safe to swim in a pond with bog filter? Any recommendation in terms of making the pond suitable for swimming? Also how do we reduce the population of frogs who love the pond more than you :-) Thank you very much!
I’m happy to swim in my pond but I can’t tell someone it’s safe to swim. That’s a choice we all need to make individually. At the end of the day all natural bodies of water have bacteria some good, some bad. My theory is encouraging more good ones to outcompete the bad. In regards to the frogs I don’t discourage them at all so I don’t have any tips or tricks on keeping them out sorry.
@@Ozponds Thanks for the answer. I think my pond is becoming a community center for frogs! Lol :-)
😂 I know what you mean. I like it though 👍
Any idea where i can get wolffia?
I’m not sure what that is?
Whenever i have green water, the nitrate is 0. It's AWESOME!
I just had a fish breeder drop off some fish. She loves green water too.
I want to figure out how much heat it can reflect and how much CO2 it can create. I don't get why you're talking about nitrogen if you already have adequate filtration.
That would be interesting. Let me know what you find out 👍. The point about nitrogen is if you have too much, you don’t have adequate filtration. In my opinion anyway. Some people are happy doing regular water changes. My point is that if the biological filtration is right you won’t have green water.
Just had to pump out my pond an fill it back up it sunk an we lost a couple, it’s our 1st time with a pond
First pond is a learning curve.
@@Ozponds now they are happy just being outside in dark with security light on they are swimming around on top , happy an it’s not warm , wish I cleaned it out before, it’s easy when you have a good pump to get all green water out, cleaned filter , it’s like new again
I heard green water helps fish feed as well (as fish food), and also keep them safe from predators. Goldfish grows better and healthier in green water. Fish prefers green water than clear water. The only con is for fish viewing.
You are pretty spot on. Most breeders will keep their fish in green water. It’s fine for the fish just no fun for us hobbyists.
