Well, we're putting the cover back on the above ground pool and we got to talking about getting rid of the ugly thing next year. Tired of the maintenence, cost and chemicals of it, but our 7 & 11 yr olds don't want to give it up. Does anyone know anything about natural pools? I remember seeing something in a magazine a while ago about self filtering ponds that are safe to swim in. My husband is almost finished building his front end loader and is ready to use it. Any advise is welcomed!
