I have just set up my Rio 180 and put in some rather cold water that I left with the heater on overnight. I woke up and opened the lid to find a massive amount of condensation all over the lid and lighting unit. I had a little search on the web but I couldn't find anything saying that the lighting unit is ok with this or not, could someone please tell me if it is safe. At the moment it is not plugged into the mains and I am unsure whether to plug it back in or to dry it off first...
