What keeps a pond in balance?
Complete the pump/filter/return route. Unconnected pump setting cannot circulate water.
A pump circulates water through a filter and helps oxygen enter the water. Plants produce oxygen in daylight but respire all the time, including at night. Fish and decomposing leftovers consume oxygen. Balance matters more than adding more of everything.
Bounded conceptual steady-state oxygen and clarity balance, not a real pond forecast. Plants respire day and night; light adds photosynthesis. Broken filtration stops modeled circulation.
Keep oxygen at least 5 mg/L and clarity at least 60% with a connected filter loop.
Balance circulation, oxygen and clarity for pond life.
