Hi all,\nI joined this group years ago, but after awhile and my pond was established, haven't been on here. I've had my above ground pond for at least 10 years. Been while, I forget! In all these years, my pond has never been green. It is now. I hopped on to see what everyone had to say. Here is a photo of my pond currently. Always kept about a dozen goldfish in it. Just replaced my pump. We had a really mild winter. I am in KY and it hasn't warmed up enough for the lilies to come out much yet. I have mini cattails, Flags, and a plant I do not recall the name of that blooms red! My pond looks great in the summer. Slow start this year...and that green water.
