Winter Pump Placement: Balancing Aeration and Temperature

A Maryland pond owner with a 4'x5' kidney-shaped pond (22-24" deep) runs a pump with two outputs: one at surface, one at bottom. Robyn approves surface agitation for gas exchange but cautions against excessive bottom flow that could disturb resting fish or over-mix temperature layers. She suggests lowering the pump intake to 1 foot below surface for better balance.
