Sunil,

Are you making fun of my fish! Just kidding. I did overfeed them but the problem is it was hard to judge how much to feed them as a weekly inventory like they do in raceways was out of the question. They also varied in size when I got them so that made it difficult to know how much ot feed them. I tried to feed them to satiation but they were never satiated!

I personally believe Wood's lack of a hole from the diffusion is exactly what Bill elluded to. The air is to scattered with the soaker hose and not concentrated like a diffuser. I have still maintained a hole in the ice when it was below zero here but it was much smaller than when temps rose.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
