Why Do Home Ponds Need All This Technology? Natural Ponds Don't
Greetings from Southern California!
I am new to pond culture, but have maintained small, indoor aquariums in the past.
We have an oval-shaped pool in our backyard that is about 10-12' deep at the deepest part, and 4' deep at the shallowest part. We'd like to stop adding chlorine to the water, and then eventually stock it with edible fish.
I've been reading a lot about providing moving water, aerating pumps, filters, vacuums and other technological inputs. Why do we need to use these things? Natural ponds have plenty of healthy, edible fish in them without needing any technology whatsoever.
Do I just need to plant more aquatic plants, and use niche animals such as detritivore crayfish, bottom-dwelling catfish, algae eating fish, snails, snail-eating fish, etc?
