having kept aquariums (big ones 220G), I never understood why so many people take a water tight glass box and drill a hole under the water line for a sump, then complain about how to deal with leaks, cracks in glass, power failure issues, cut off switches flow rates etc...
I'm new to ponds but why put a hole below the water line in an already water tight liner or cement pond. It's just asking for problems with far more money available to spend elsewhere on the pond.
my 2 cents
