So my dad and i are planning to make a above ground pond. He said that he wants to make a filtration system with out a pump. I told him it wont work but he insist it will work? What do you guys think????
i don't see how you would make the water flow into the filter without a pump of some sort, so i don't think it would work very well.
most filters use a pump to either get water to the filter or get it back from the filter you'll need a pump to perform one of those functions (but never both).
well actually i correct myself i just thought of something. I used to have this old magnum when i turn off the motor it still runs. The flow rate wasn't great but it worked...
