I am going to go with this approach of less on the bottom and see how that works out today. I shoot the surface temp and i have 80degs. I shoot the FW and i read 110.

After seeing the "removing a UTH" thread above I was thinking of abandoning hope on the FW since I have a UTH stuck to the bottom of a tank that I used to keep hermit crabs on, which is doing nothing but sitting in the closet, and just switching to the ZooMed UTH...

But since I spent the $8 on the FW I'll keep at it (but if I can't make it work I'm not going to cry over the $8).
