I'm wanting to get some sort of pond heater for my 450g and 250g ponds, but my dad doesn't want to use alot of electricity. I've tried runing water through black piping and running water over pondliner. Should I go out and buy a cheap solar pannel and heater? I have turtles in the ponds which is why I'm wanting to heat them.
Thanks! :)
Thanks! :)
