Hey, thanks for the link! My basking temp seems fine, but water temp is too high at 77f, which I knew, but I can't seem to lower it. I normally have it at 73-74f, according to info found on ATP, though now it seems even this may be a tad to high. The heater has been off for days and though I know the weather has been warmer just recently, we used to live in the south of France which is far hotter than here and never had a problem. It is very frustrating........... he is still basking, though perhaps not quite as much, so maybe I'm worrying too much. Thanks for the info!
