Pond Boss Forums AQUATIC VEGETATION Identifying plants Film over the pond

My newly emergent watermeal swirls in patters like you've described as well, but I know what I've got and know that if my tilapia don't get here soon, I'm gonna have to resort to chemicals! However, pollen does that as well and won't grow, so if you're seeing a generally consistent appearance, my money is still on pollen. My WM has grown enough over the past week that I see the change, and I think most aquatic vegetation would have shown at least some change by this point in your pond if it were anything besides pollen. We'll await your pics.
