So over the weeks, my pond has become more green and green. There is also some white stuff forming around the plants. I assume this Algae from the sun, but I'd like some expert opinions on what it is and what to do. There are 2 turtles, an RES, and a Belize Slider, plus a few Comets, minnows and 2 Carp.
The last picture is the water coming out of the filter.
