This thing has been giving me a fit. I finally had it steady at -250, then two days later it goes to -475 or the other extreme at -94 etc. This thing is driving me nuts!!! Any advice?? I have been running this on my tank for about 3 weeks now. The guy at the fish store had run it on his tanks for about 3 weeks to get it going. Please help.
