Yes plan on aerating and feeding. Water temps were measured from a small test pond before the larger one was dug. I thought I had springs based on the test hole, however the area is basically a large thick clay slab with sand on top, so the water sort of flows through the property in the sand. I will have to see how my temps do this summer because only the upper 2-3 ft of water is the sand and the center is dug into the clay. Still have good flow of water in and out but I am thinking it might behave differently this summer. Have not found too many places to get warmouth, still looking.
