Do not have electric outlet so no filter yet, looking into how to hook up a solar powered pump and a filter system
I do have a slow exchange of water, have a faucet that can not be turned all the way off, so hooked up a drip hose, mounted it up on a tray a couple feet above the largest pool, the water sprays into that one, falls into a second one, drips from there into a large potted plant and then into the pool. The water from this one goes through a tube into the second and from there into a third. Lots of plants take care of the rest
