I recently stayed with a friend in Brazil who has a big property right next to the rain forest with 3 ponds of Artesian Water.
Would pumping right from an actual pond, not a fish tank or man made pond, work for an AP System? Has anyone even done something like this?
I was wondering if there would be enough ammonia and what not to grow the bacteria in the system?
There are fish in the pond but it's not stocked to be 1 lb of fish for every 5-10 gallons of water or anything like that.
I've seen this done and working fine. I suppose you wouldn't be raising fish to eat--at least fish that were not in the pond. Or frogs or turtles or crayfish or whatever floats your plants. ;)
I also saw a video on youtube: the AP system was in the back yard in Australia. It was connected to a fish tank and a pond.
