I found this forum when I was researching how to build a bog filter for my little stock tank pond. The pond bug bit me a few years ago, and I haven’t looked back lol. Right now I have a 40 gallon stock tank pond and a 35 gallon pond container that’s new this year. Just waiting on the weather to warm up so I can start planting. Here are a few photos of the oval stock tank pond and the fish, and the new pond.
