Daniel Posted January 4, 2021 Share Posted January 4, 2021 UV inhibits the reproduction of the free floating algae that make the water green but it won't kill the currently existing free floating green algae. So, perhaps it will take longer to begin to have an effect. Alternatively, if the free floating algae reproduces at a faster rate than the UV can depress reproduction it may have a hard time ever catching up. 1 Link to comment Share on other sites More sharing options...

FrozenFins Posted January 4, 2021 Share Posted January 4, 2021 I am dealing with green water too, a method I found and am using right now is to get more plants. I got some amazon frogbit, and hopefully that wil help along with regular waterchanges. The plants will use up all the nutrients that the algae is and then the algae will soon die off.

Colu Posted January 4, 2021 Author Share Posted January 4, 2021 (edited) I have tried that with with duck weed had no effect maybe I have a mutant form of algae try everything in last 4month sometimes it clears but come back in a day or two Edited January 4, 2021 by Colu Link to comment Share on other sites More sharing options...
Daniel Posted January 4, 2021 Share Posted January 4, 2021 Green water is usually a result of generous nutrients in the water and enough light to support rapid free floating algae reproduction. Without one or the other the free floating algae eventually cannot reproduce and dies. This is the point your water goes clear. The aquarium that produced the green water for the video below is clearing up today because it has had reduced light recently as it has been cloudy for a week here in North Carolina. 2 Link to comment Share on other sites More sharing options...

Daniel Posted January 4, 2021 Share Posted January 4, 2021 @Colu what do you think is the source of the green water? It looks awfully green in that photo above. When I have had water that green, there was plenty of light and plenty of nutrients. Yours could be different though. Link to comment Share on other sites More sharing options...
Daniel Posted January 4, 2021 Share Posted January 4, 2021 @Colu you mentioned a foot long goldfish in the aquarium. Do think it is possible the waste products from the goldfish are feeding the free floating algae that makes the water green? Link to comment Share on other sites More sharing options...

Colu Posted January 4, 2021 Author Share Posted January 4, 2021 I have enough biological filteraition to remove nutrients Link to comment Share on other sites More sharing options...
Daniel Posted January 4, 2021 Share Posted January 4, 2021 Just now, Colu said: I have enough biological filteraition to remove nutrients I suspect that you do too. But part of that biological filtration might be the free floating green algae. It seems to have been okay for the last 4 months without starving to death.

Daniel Posted January 4, 2021 Share Posted January 4, 2021 What kind of results did you get the first time you tried that. Did it set the green water back any? I might be inclined to try that. Are there other plants in the aquarium? Link to comment Share on other sites More sharing options...
Colu Posted January 4, 2021 Author Share Posted January 4, 2021 (edited) It improved but for about 1week and then came back that was before I got my UV cleariser duck weed and some some plant I can't remember name of can't have a lot of plant just get up rooted and eaten Edited January 5, 2021 by Colu Link to comment Share on other sites More sharing options...

Colu Posted January 16, 2021 Author Share Posted January 16, 2021 Just thought I give update it took 12days but my tanks water finely clear had to do extra water changes to remove dead suspended algae in water column. My fluval uvc inline clarifier worked just took longer than I was expecting Link to comment Share on other sites More sharing options...
