thanks for the info, trying to figure this thing out still, finally figured out the right probs but when I moved them everything went haywire.. the humidity that was reading at almost 80% tanked out to under 30% when I moved it from one corner to the middle of the tank and the temp went from 82 down to 76 from just moving the probe about an inch..idk what is going on but will prob buy something else when I get my stipend next month and just keep this one as a temporary back up. I think I am going to try and put the probs in the larger tank and not the small one hes sitting in maybe that will help sort it out, no worry about accident spraying etc.
