Excellent job! Please keep us posted on the results. This is turning into a great experiment for everyone in the northern climates. If you can overwinter tilapia in such huge numbers, everyone could keep a few to help with plant and algae problems (where legal). It will really be interesting to see how long your season above 58-60 degrees will be. Great experiment. I am sorry I was doubtful earlier. I was wrong. \:o Foot in mouth graemlin!

Please no more rain for a month! :|
