My 6500 gallon pond runs on aquaponics, and absolutely no water changes, although get water top-ups and a biannual filter maintenance





Yes, only the inlet is pumped, gravity does the rest.Very interesting. So you pump water up to the first container, then it trickles down to the container with the huge purple Taro, which I love btw! Then it goes into the main pond?
This is the pond at home, only petsI'm trying to understand what I'm seeing in your pictures. What kind of livestock do you keep in it? Do you raise the fish to eat, or just for pets?
Tropical climate this part of the world, highs can be 42deg celcius and lows can be 16deg celcius, the pond is 6' deep so not much variation is observed.What is the annual climate like in your part of India?
