Hi! So I talked to the lady who runs the place where I volunteer (I am a high school student) and outside in the back they have a nice garden and a pond! I'm not sure how big it is, and I will post pictures later when I bring my camera. She said I can use the garden as much as I like and I am planning on cleaning up the pond and getting whatever I need for it. I'm just wondering if someone can give me the basics on how to start cleaning the pond, how to take the water out, and what filter I should use for it?
