new pond owner what to do for winter
Built the pond this late summer, 30 square feet, seven goldfish. Have a used pump bio filter system that seems to pour a trickle of water into the pond but keeps water clean. I tried to catch them (fish) to bring inside (before I got the pond they lived for years in large plastic tubs) but no sucsess. I doubt that water flow would continue in the winter as so measly. Should I get a de icer I hear they are very expesnibe? Other options?
