Hello, all. I'm new to the forum and really need some input on my koi pond. I installed the pond last year and have had nothing but problems. My koi do fantastic, but my water, pump, and filtration are driving me insane. What type of pump and filtration do you recommend? I am currently using a swimming pool pump to draw the water and run it through my filtration. I have a milk crate wrapped in netting that the hose goes into under the water. It then runs through the small filtration basket, and out into my filtration bin. Then the water goes back into the pond relatively clear. I am also using Aquascape granular algaecide, which has helped tremendously. Over the course of this ponds life (16 months!), I have used a large sump pump to draw water, and 2 pool pumps. They have all burned up. I just read someones post saying they have had their pump for 25 years! Plead help me keep my sanity and point my in the right direction.
