I am a newbie to this pond thing. I have searched and searched for the answer to my green water problem and hope that someone here can help. This is the first year. I'm in full sun most of the day and just recently added plants. I took a pH reading and I'm very high. So how do I go about lowering my pH. I had a pump circulating the water until recently. The frogs/toads found me and now I have all kinds of tadpoles. I was afraid by running the pump the tadpoles wouldn't survive so I turned it off. I bought a couple of feeder goldfish to help with any mosquito larvae. So my question is How do I lower the pH to get rid of the green water? This is the only picture I could find right now, trust me it looks a lot different now.
