In my backyard I have this little waterfall pond, its very small. Well one day the air pump stopped working and we felt it alone for a few days. I noticed frogs hanging around and there and eggs floating on top of the water. About a week after that I seen quite a lot of tadpoles, the water is very green and thick with algae plus, I do not want to have a breeding pond for mosquito's. At this point I don't know what to do, I want to raise this tadpoles in an healthy environment and to get rid of the mosquito's also.
So the question is, how do I clean this water without harming the tadpoles and frogs?
