I’m new here and I wanted to try to find a solution for the dark water in my pond. The pond was dug last summer and it is spring fed from the bottom and the pond is a ledge rock bottom. There is a above grown spring that also runs into the pond. Basically in my back yard, there was a spring that ran out of the ground, but it just ran across my yard and water just laid stagnant and the yard was all mucky. So I dug it out and tried to do my best to make it better. I bought a 8000 litre per hour waterfall pump and I want to try and clear this water up. What should I do ? I’ll take any advice, thank you
