Hi all. I need to share...I have been dreaming of creating a pond for 30+ years and finally have done it. It is 35L x 20W x 4D. My pump is 9000 gph. The Wetland filter is 8L x 5W x 6D which feeds into a stream 27' long. I have 4 Waterfalls along the stream. I pull water from an undergravel filter as well as the homemade skimmer. The water is crystal clear. Currently we have about 18 goldfish in to eat the algae. In the spring I want to get some Sunfish to keep the goldfish under control. I have one problem...I never want to leave my patio! All I want to do is sit by or play in the water. As soon as my wife gets home she is also in it. It's a tough life.
