Hello, this is my first time posting at this site. I need help. We built a pond last year and had beautiful water until the first part of this year. Now it is kind of like chocolate milk. We have fathead minnows, coppernose brim (put in fingerlings last year) and tiger bass (6" put in last month). We read this site and got a feel for what we needed to do as far as the jar test. Our pond is about 90 feet wide and 300 feet long and is 10 feet in the deepest part. Yesterday, we put 400 lbs. of hydrated aluminum sulfate and 200 lbs. of hydrated lime. Within a couple of hours it started clearing and you could see 18 to 24" on the white disc. At 10:00 p.m., it was still as clear if not a little better. At 5:30 a.m. this morning, it was chocolate milk again. We have a vertex bubbler which we turned off thru this process(what was recommended). What happened, did we not use enough or do we need to do it again and if so, how soon?
