Hello everyone! I know this is not a new topic, but I’m experiencing a unique problem. I have a 1 acre pond that’s about a year old. Like most new ponds I still have a fair amount of clay sediment making my pond cloudy. I have about 6-10” of clarity, and it’s not improved over the last 6 months at all.
I’ve been testing out the best solution to get the suspended clay to settle. I’ve been using the jar test with 4 1-gal glass jars. I tried gypsum first, but didn’t see any results.
Here’s where I’m struggling. I tried the jar test with aluminum sulfate. The aluminum sulfate does a great job bonding with the suspended clay, but instead of the larger particles settling at the bottom of the jar they actually rise to the surface. The water is extremely clear, but now I have all the sediment sitting at the surface. Does anyone know why that’s happening, and more importantly how to fix it? The water is testing to be extremely hard as well. Any suggestions would be appreciated.
PH: sitting about 8
Carbonate ppm: 240
Total Alkalinity ppm: 180
Hardness ppm: 300
