How to make an aquatic plant water filter? Answered
I'm making the kids a wading pool out of a poly water trough. I want to filter the water through a separate trough filled with aquatic plants with probably shale as the base. Not too sure how to set up the filter though. I want to recycle the water through both. I don't want to use chemicals and this will also be a proto-type for a chemical-free swimming pool when they are older. Help please!?
