The 50g is part of a system, the chiller 1/4h in line. I know others have kept them in warmer water but I'm thinking mine aren't happy and will drop the temp, see if I can get it down a few degrees at a time. It seemed like it would never stop running the last time I tried but I'll change a few things and give a try this afternoon as I watch this never ending flurry of basketball, thanks, 77 here we come.
