Does anyone own or have had any previous experience with a tropical fish pond? I live in SoCal and love tetras so I recently started a 300 gallon above ground pond that is heated by 3 500 watt heaters and has a large pond filter. It is also in a shaded area with lots of plants like anubias and Java fern. I have not been able to find anyone who has had a pond of this type. Any tips are greatly appreciated.
