Hey all, So as a summer project I'm looking to set up a container pond in my parent's backyard. It would be a combo of my dad's garden/plant hobby and my fish/plant hobby, so it's perfect! Running into a couple decisions and problems getting started, so came here for a little help! #1: What type of container? I've been looking around online with mixed results. Some use galvanized tubs, others use plastic tubs and others use fancy garden pots! We're looking to be around the 30-40 gallon range, any suggestions? Below are a couple links that I've been considering... Amazon.com : Behrens 7 35-Gallon Round Steel Tub : Planters : Patio, Lawn & Garden Amazon.com : Tuff Stuff Products KMT102 Oval Tank, 30-Gallon : Patio, Lawn & Garden #2: Filtration: Thinking about creating a bog filter, where I pretty much just pump water into a pot with bog plants, which then waterfalls into the rest of the container. Does that seem enough for the body of water, or too little? I have extra air pumps and water pumps, so many things would be possible! #3: Stocking: I showed my dad White Cloud Mountain Minnows, and he thought they would be neat. Any other fish that anyone recommends for a 30-40 gallon volume? We live in Wisconsin, so it would have to be able to handle some temperature variations... #4: Cover: This will be in my parents shady backyard, so I'm not too concerned with overheating in the sun, but it will need cover from predators (raccoons etc). Any suggestions that wouldn't make it just an eyesore? This is an ongoing project, so will be looking for advice for quite awhile here! Thanks for any pointers or advice in advance!
