My bf and I want to make a reasonable sized indoor pond for koi fish. We want it as Eco friendly as can be. We have no clue where to start or what works best...any advice or ideas will help us out.
New to this any advice.

4x4 small starter pond. Working with wood we like the look square shaped. Mainly want to stay under $200
If you made the hight 2' that would be 230gallons. That'll be OK for a few koi for a little while, but they'll outgrow that. Yeah a wood frame, plywood interiors and slap a pond liner in and your done, do a little research here lots of information.
Okay great any ideas on a natural filter? We were thinking of putting in a few water plants a fountain and some snails as well as an algea eater. Do we really need a filter?
You'll need a way to remove nitrate from the water as it's toxic to fish. Also you'll need to remove the solid waste, I.e uneaten food and fish waste. Plant filtration is very good at nitrate removal, there's a thread in the setup and filtration section here. To remove solid waste you could use a gravity fed strainer. Now depending on how often you want to clean the strainer, you'll have to decide how fine a strainer you want, the finer the strainer the faster it'll clog. Even with a lot of plant filtration you may need to add some me bio filtration.
If your pond is above ground heres what I would do.
2x1" pipe put in at the hight you want the water to sit in the pond, this will provide surface skimming. Then these pipes, or intakes, will gravity flow about 6" into a diy filter, this could be a large, firm bucket with some filter floss(or blanket stuffing, just make sure its got no chemicals in it) held in place with some egg crate or light diffuser. Then it'll flow into alot of pot scrubbies, you can get these at discount stores for cheap. That'll be the added bio filtration. From there it could flow via a 2" pipe into another container filled with plants. If you section off the plants with some more egg crate you could put the return water pump in the same container.

Well defenitly look into that section and read into it more. But what you just said sounds easy to do.
Thanks for the helpIt is lol. Tbh its a basic sump design, but better suited to an above ground pond. I learned all I know on here, just research and have fun
