LOL! Free time? What is free time? j/k. I know they can be alot of work, I'm ready for that I think. Your backyard pond sounds like it will be nice. Thanks for that link too, I've book marked it for future references as well.Hunter said:How much of your free time do you want to lose?
They are a pain in the ass, I currently have a small one(500 gal, plastic molded containers) in the front yard. it is about 3 feet deep, about 10 feet long. Keep goldfish and plants in it during the summer to help keep the water clear, but it does not do a very good job, my pump and filter sucks and not in a good way. You really need a good filtration system and a dependable pump.
Currently building a larger pond in the back yard, this one is currently 6 feet deep and will be about 20 feet in circumference, will have a waterfall fish and plants. hoping it will be big enough to have the fish stay in the pond all year.
No pics as of yet, I am sure it will take me another 2 years to finish it.
Here is a good website that will give you some ideas on how to build one.
