ABOUT 3 YEARS AGO I PUT A SUMP PUMP IN THE WATER AND RAN IT ABOUT 2 HOURS EVERDAY IN THE EARLY AFTERNOON TO BREAK A HOLE IN THE ICE. THE ONLY FISH I SEEN THE NEXT YEAR WERE LITTLE MINNOWS AND SMALL BULLHEAD. WHICH I DIDN'T PUT IN . I DON'T KNOW WHERE THEY CAME FROM.
THIS TIME I PUT IN A SMALL AIR PUMP TO . IT WASN'T ENOUGH TO BREAK A HOLE IN THE ICE SO I ENDED UP RUNNING THE SMALL AIR PUMP FOR 7 HOURS DURING THE DAY AND RAN THE SUMP PUMP FOR 2 HOURS ADAY . I THOUGHT THAT IT MUST HAVE HELPED BECAUSE WE SEEN HUNDREDS OF 2-3 INCH FISH IN THIS SPRING IN APRIL BUT WE WENT UP THE END OF MAY AND WE DIDN'T SEE ANY SMAL FISH. I DON'T KNOW IF THEY ARE GONE OR MAYBE THEY ARE AT THE BOTTOM. ITS HARD TO TELL NOT BEING THERE THAT MUCH.
MY POINT IS THAT MY UNCLE HAS THE SAME AIR PUMP I HAVE AND HE ONLY HAD TO RUN THE AIR PUMP OVER WINTER AND HE HAD ABOUT A 4 FT HOLE THROUGH THE ICE. HIS POND IS ABOUT 14-16FT DEEP MY IS ONLY ABOUT 7-8FT SO YOU MIGHT NEED A BIG PUMP OR RUN A SUMP PUMP LIKE I DID SINCE YOUR POND IS 7-8FT DEEP ALSO. LET ME KNOW HOW IT WORKS OUT FOR YOU THIS WINTER.
