Natural Outdoor Pond filtration?

christy s asked:
I really want to make an outdoor pond this spring/summer for my two goldfish. I was wondering if it’s possible to make it more natural and not have to have a filtration system? Like having a ecosystem in my backyard, if that makes any sense?
Any ideas or tips would be great and if you could recommend some books that would be great too.
Thank you~
Well right now they are small.. I got them in sept and had them in a 3 gallon tank til now.. yes i am a mean person.. but they are in a 20 gallon now so I am sure they will grow fast now hence why I plan to get them in a pond.
Why do I have to wait til they are big before I get guppies to eat the mosquito larva?

You could, but it’ll look green and scummy. Which is actually the way it’s supposed to be, but people don’t like the look of it. Just put some plants in it and if your goldfish are big put in some guppies to eat off the mosquito larva.
Edit: Any standing water can become a breeding area for mosquitos. So, you want some fish to eat them. Guppies (also called mosquito fish) are small and cheap so people usually use them.

Without some kind of filtration, outdoor ponds tend to have algae blooms which are not very attractive. Use of aquatic plants and providing shade for part of the pond can reduce this, but to support fish properly, you really need filtration and aeration. But goldfish aren’t very demanding, so it can be a pretty simple system.
EDIT – they will grow FAST in a pond. They don’t eat mosquito larvae so you need mosquito fish (related to guppies) to take care of that. But beware – mosquito fish and guppies breed like crazy – so only get a couple – and if you have them, you won’t have tadpoles – which is why we got rid of them and use other methods of mosquito control (mosquito grow inhibitor called a mosquito dunk).

you should look up backyard eco systems. Sand filtration systems work too, its important to have a pond with rocks of all sizes in it so that there is a place for algae to do its thing, its important to have a balanced pond with the right mix of creatures and plants to keep the water green and clear. The filtration system isn’t the issue, the oxygenation of the water is whats important. We tend to use a waterfall type combination filter to keep the water areated so that there is plenty of oxygen in the water for the fish. Email me anytime, I will tell you of my success’ and failures…obviously the success’ won!
