Here are the one week results. FA on two banks has been eliminated almost entirely. They seem to be working their way around the pond clockwise. A little algae remains in the shallow end but they have reduced it by more than half. No chemicals have been used since last fall. Probably the most surpising is their impact even with the relatively cool, 64deg., water temps.

I'm not sure if I should give the tilapia 100% credit. The tadpoles seem to be eating algae too. If you look close you can see them in the upper picture as well.
