Hi, I am Erin from SoCal/Mexican border with a mild climate. My pond has approximately 1200 gal. I have so far 3 adolescent turtles and water plants and a cat fish in there. Given my mild climate, I want to put more tropical fresh water fish in there that require a temp around 72 degrees. Now my question, is there a way to disable the auto shut off of a pond de-icer or to adjust it to a higher temp? I would like to hook it up to solar and have a steady temp. I dont want to use 5 aquarium heaters a 250 w if possible. Any suggestions/experiences?
