not harmful; causes dangerous water quality changes common in ponds greater than one point five meters deep, rare in shallow ponds formation of two distinct water layers:
Epilimnion (warm surface layer)
Hypolimnion (cool bottom layer)

Effects on Water Quality sudden mixing can cause:
rapid oxygen depletion accumulation and release of toxic substances - methane and hydrogen sulfides gases fish kill
