Message: [QUOTE="Nevermore44, post: 469600, member: 4049"] My pond is around 1k. I have currently 1 wakin goldfish and then 10 koi ranging from 16 down to 8 inches. As originally planned, each year or two I re-home one koi as they get bigger. I feed them one to two times a day. My water is clear and my numbers are spot on. What makes it work for me is the sand and gravel filter and secondary shower filter I built many years back now. If you are semi handy, they are easy to make and don’t cost a lot. Now they aren’t pretty compared to bog gardens, but you can set them up away from the pond since they only rely on gravity for a return and they do an amazing job of physically removing debris and fish waste as well as acting as giant bio filters reducing nitrates. Having to haul out of the pond and clean pad filters is an absolute pain which makes one not want to clean them… which leads to water issues… which leads to fish health issues. The sand and gravel filter is easy to clean and doesn’t take much time and you don’t have to even get your hands wet if you don’t want. With the heavy fish load and feeding I clean mine about every other week or so to keep my nitrate level down. I never have a blip of ammonia or nitrites. Here’s a pic of the pond. It goes under the bridge there and to the left. It’s three feet deep at the lowest area where the submerged pump is. The filter set up shows the 55gallon drum on the left is the sand and gravel filter which then spills over to the smaller shower filter drum that has feather rock. I’m planning on eventually moving them both around the corner of the home by my rain barrels. I have the “cage” opened up here in the pic. Typically it’s down to protect from the herons.
