I am going to start building a bog for our 700 gallon above ground pond. I have an idea of what I want to do. Not many pictures online that I can find. If any of you have an above ground bog, can you share your pictures? Not liking these canister filters. I had a bog I made out of a 20 whisky barel liner. That was too small and it was hard to maintain the plants in that small space. Water is cloudy all the time now. The main reason is that I have too many fish. I am in the process of getting rid alot of them.
