It has now been 36 hrs since my last Alum treatment and visibility is at 16" on the edge and 18" in the middle. It seems to cloud up a little bit overnight because in the morning visibility is around 14". Why does it cloud up at night? The pond still looks a little brown at times, but for the most part it the color is turning to more of a light green color. It looks the best in the evening right before dark.I took a sample of pond water last night and let it sit overnight and it didn't clear up any so clarity my be as good as its going to get until I add more Alum. I am going to hold off for a week or two and see it improves any more before another treatment. I fished this morning for about 30 minutes and the fishing still sucks. After I fished,I threw some fish food and they ate fairly well, but nowhere near how they used to before Hurricane Rita came by and screwed things up. Right after the hurricane hit my pond was beautiful and clear and shortly after it went to crap and hasn't been the same since. Hopefully, I am making the necessary steps in getting this pond beautiful again. Thanks for everyone help and advice. Please, don't stop. I feel like I am half way there because of this wonderful site. Thanks everyone...
