Jorge54 Posted September 9, 2021 Share Posted September 9, 2021 Hello, For Several weeks I been dealing with my tank water becoming super green. I've done a few water changes and just gets green after 2 to 3 days. I turn the lights off and it clears after a week but comes back when light are on. My plants are also dissolving. I use the iron, algae,easy green and flourish potassium. Link to comment Share on other sites More sharing options...
Guppysnail Posted September 9, 2021 Share Posted September 9, 2021 (edited) I’m not a balanced tank expert some will chime in. I can tell you a Quick fix but it will not solve why it repeatedly happens. Quick fix vacuum substrate thoroughly and large water change. Get a cheap internal or hang on back clip on uv light for the quick visual fix. When the experts chime in I would definitely listen to there long term actual solutions. Best of luck 😁 Edited September 9, 2021 by Guppysnail 1 Link to comment Share on other sites More sharing options...
Griznatch Posted September 9, 2021 Share Posted September 9, 2021 (edited) Need a bit more info, size of tank, location (is it by a window), what kind of light are you using, and how long is it on? Not that this helps you but.. wow, I wish I could get that green water 🙂 Edited September 9, 2021 by Griznatch add more 1 Link to comment Share on other sites More sharing options...

JettsPapa Posted September 9, 2021 Share Posted September 9, 2021 The best method I've found for battling green water is to add as many live plants as you can and limit light to 6 hours per day. 2 Link to comment Share on other sites More sharing options...

Tihshho Posted September 9, 2021 Share Posted September 9, 2021 Looks like you're getting too much sunlight too. So no matter how long you have the light strip off for you're going to have this issue until something is sucking up all those nutrients. You might want to consider closing the blinds in that room. 1 Link to comment Share on other sites More sharing options...
FrozenFins Posted September 9, 2021 Share Posted September 9, 2021 It defentley looks like its the windows fault. Perhpas try to add a curtain, or with black paper you can block the sides of the aquarium that are getting the most sunlight. I found that when battling green water the best way to fix was to block out all light till the green water was gone. I simply turned the aquarium light off, and covered the aquarium with a towel. Leaving 0 light in the aquarium. After 5 days nearly all green water was gone. And by the 7th day the towel was taking off. If you dont solve your sunlight issue you will see green water again. 1 Link to comment Share on other sites More sharing options...
Brandon p Posted September 9, 2021 Share Posted September 9, 2021 If you can’t control the outside light you will have control your light. If you can just turn the light off or covering part of it. I would also try adding topwater plants like everyone’s favorite duckweed. It goes crazy, blocks light and sucks up lots of nutrients. I use duckweed in outside ponds. I have a 20 gal that is centered in front of the window and I use frogbit in it and keep the water dark with tannis. Plant choice helps as well. If I have a hi light spot I like to use fast growing plants and moss. Also if you can’t control the light as much as you like, I agree a UV HOB will also help but isn’t the sole cure. here is mine. The water is a dark tea color even though it does kind of look green the pictures. A few swords, pennywort, frogbit and moss. I have a new moss in there and I’m not crazy about it. I have a hygger light on it but it rarely comes on. Sorry about the mess I am working on a few things. 1 Link to comment Share on other sites More sharing options...
