Hey there My name is Al and I am from Long Island , New York ( USA) I have a nice oval pond about 1000 gal in my back yard, always looking to improve my pond. My latest project is converting a 150 gallon rubbermaid stock tank into a bog filter with waterfall. I have been racking my brain how to connect a waterfall chute that wont leak as well as putting in a manifold in bottoc of container...driving me nuts but I am committed to finishing this. I saw sone rubber maid containers with the waterfall but cant figure out what they did...Can anyone offer e some ideas, tricks ways to make this bog filter or articles to read??? would appreciate it!
