Need help! This spring is the second year for my pond as I set it up last spring. I have 6 small koi in the pond and a few goldfish, also one big lily plant. Everything was great last year with clear water and fish doing good. Fish and lily plant are doing great, but the water has turned green. I have a good filter with different filter and bio media. What are my options for getting rid of the green water? Why did the green water start? Hopefully someone watches this forum and knows more about ponds than me. Thanks for any help, Daryl Here is my pond and some closer photos of the green water.
Thanks for the reply so quickly. For sure not too long man, thank you for thinking it through and giving me good advice. My local fish store guy gave me similar advice but I wanted to make sure he wasn't just trying to sell me stuff if I didn't need it. You were dead on about the leaves. I have a bunch of trees just out of the photo on the left and they shed a lot of leaves into the pond last fall. I was going to clean them out but was waiting for the water to warm up before I got in there. Then bam, green water and couldn't see anything. My pond is about 1000 gallons, what size UV do I need and do you recommend any brands?
I bought the Jeabo 55 watt and installed it on Monday and by Wednesday evening the water was clear. I can't believe how good this thing works! These aren't even good pics as the sun was going down, but you can see how much clearer the water is and it is even clearer this morning when I looked out there. Also two of my fish have gotten huge since I last saw them over the winter.
Thanks for the replies Here is some photos of my pond from today. Water is so clear I don't think the fish are used to it yet they are hiding under the bridge. I am still working on the pond filter and some more plants in the pond, but this is what it looks like so far.
