My pump has been running now for about 24hrs. I have walked the banks and saw no sign of living fish. My son came over this afternoon and said he saw fry in the pond. Just for the heck of it, I walked the banks again and then tossed in some feed, closed to the stream of water coming from the pump. Guess what I saw? TILAPIA! So if they survived, then maybe others survived also. I stood there and watched for other species to surface but I only saw the tilapia and small maybe 1" fry poking at the pellets. Wish I could have gotten the pump in sooner, but to see live fish in the pond was worth the 316.00 for the pump and pipe. This is great news for me, and hopefully I will see more fish as the pond condition improves.
