I am just starting to look into aquaponics, and had an idea, but I'm not sure if it would work out. Here is my thought. If you had a large setup, would it be OK to use the sump tank as a swimming area?
In my mind I am thinking: above ground pool as fish tank, waist high grow beds, followed by a sunken pool for sump tank.
Any reason why it wouldn't be beneficial to swim in the sump tank?
