Thanks BB
my incy is a Brinsea 20, I've probably used it for 10 or so hatches. The weather could affect it I guess, but the incy sat next to it is still bob on at 37.6....
ooooh Chris! I hope there's still a chance! I will have to wait till tonight to candle them, wish me luck.
I will still stop the turners today and add some water to the troughs just in case....fingers crossed
