I have a small approx 1/4 acre pond. I dug the pond almost 10 months ago and have been struggling with 2” visibility on a good day! I finally found some alum, and added my around 25 lbs via mixing and spraying evenly over surface. I followed that by 10 lbs of hydrated lime. All went well and within 2-3 hrs the results were unbelievable! I had 2’+ visibility and all the fish seemed happy and normal behavior aside from a little shy. It’s been 3 days since and I’m noticing my water is starting to cloud up again, but it’s not the same brown cloud, but rather a teal / grayish blue color. Visibility is down to 1’(+\-). My ph is balanced at approximately 6.8. I have pond loaded with bluegill and a few perch. No catfish. I plan to stock with some largemouth in the fall, but am waiting for the bluegill to spawn. Please help me
