30º might be slightly too hot? You could raise the tub up an inch above the mat to cool it slightly. Just a thought.So we're off again and the news on the two girls I was waiting for. One was just lifeless (7days in) and the other had a small tap, that looked like it might do something, planted last Thursday. I fished that one out and she's sat on the far right just to see what she does if anything. I lightly plugged the holes with a tiny corner pulled off the cubes edge. :smoking:
