Ok so I got my Rack and my Helix last nite from Reptile BAsics and I cant seem to get these temps right. I have the probe taped straight to the Flexwatt. The tubs seem to bubble in the middle. The only way Im able to get the temps to 88-90 in the tubs is to set the helix at 102... is that too high or is that normal with this rack. Please help me out so I can rid of these 3 tanks I have. I have another rack but its made completely different but it runs great.
