I found this stuff over the weekend while bucket stocking crawfish from the creek. Pretty sure it's chara, but wanted some confirmation. I had forgotten about the crush and smell test, I'll be doing that this evening. The first photo shows the weed on a 1 gallon bucket for size reference.
I will probably be removing it from the pond although it showed up on it's own and will likely come back again. The ponds in my area tend to have a PH on the basic side of neutral and our waters are also typically hard. Nutrient levels are probably on the higher side as well.
