Planning my first pond, in ground 300 gallon Rubbermaid tank, with 50 gallon above ground bog filter.
The pond will at least partially freeze in the winter. Planning to remove the pump in the winter, and run a small heater to keep an airhole but what happens to the pvc plumbing in the bog filter when it freezes solid? Pipes will have open ends but still full of water.
Will regular pvc crack, should I use the flex pvc or would that work in the bottom of the bog?
