I got my water tested at LSU and got the results back over the weekend. I'd like to hear any input from more experienced members here.
To me, the water looks pretty good. I was a bit concerned because I got the soil test results back a week ago. The soil is more concerning to me (high phosphorus among other things) but if it's not killing the water I don't know that I should worry. The results are attached here. I'll also mention I've been aerating for about a year and the pond is 40 years old. It did have lots of duckweed a year back which I've killed off.
Edit: One thing not listed on the water results which I was told over the phone is my Phosphate water levels which was 0.05 ppm.
