I'm looking at buying the UTH's for my new viv stack and now I'm reading horror stories about zoo med UTH's short circuiting and combusting. So I'm just wondering is there another brand out there that's safer to use, and also I'm planning on placing these UTH's on tile slabs and putting them actually inside the tank and held down in place with a glue gun. I'm just wanting to make sure this set up is okay with a thermostat regulating it and also what the best UTH's are out there on the market.
