Ty for the link Neelie. As far as I can tell, I'm doing everything right- but I'll be sure to record the temperatures before I start for next time.
Little- I don't have any of those readers yet, but I'll see about picking some up this weekend. I'll probably check into getting a bigger tank but my space is very limited so Phoenix may have to stick with what he's got.
I also read somewhere that it was a good idea to let the new water sit for 24 hours before introducing it. Going to try it, hopping that helps too.
