I have a pretty big backyard that my family and i have been putting a lot of work into over the years, gardening and such. I've always wanted to add a pond, but until now i couldn't decide a place. We have this cement rectangle that has been used as a flower bed over the years. Its about 6-7 feet long and 3-4 feet wide. heres a picture of it...
I began digging out the soil to see if it has a shallow bottom and it does not. I got about 4 feet down without hitting anything. So i'm thinking I can dig out the soil, add some pond liner, load it up with some aquatic plants and boom! I've got myself a pond.
However, one obstacle would be filtration. I dont have an outdoor electrical outlet so I'm not sure if I can power a pump. I have an interesting idea i want to put out there. I've been a fish keeper for a while now and I've discovered that certain fish can thrive in stagnant cold water by getting oxygen from the air. In particular, I'm thinking of paradise fish and dojo loaches. Both of these fish are known to be very hardy and in nature they eat mosquito larve, so they could help keep the mosquito population to a minimum. The pond would be well planted so I'm thinking the plants will provide some sort of filtration. I'd imagine I'd have to bring the fish indoors in the winter, but I have tanks that can take care of that.
So, is a stagnant planted pond possible? or will the water just become disgusting fairly quickly? If not possible, is there anyway to go about powering a pump without an outdoor outlet?
thanks!
