Much appreciated, I will pick some of this up today. My Herpstat 2 finally showed up, so I'm planning on tearing everything down for deep cleaning, then rebuilding with the Herpstat probes installed between the glass and the UTH, and under a CHE, rather than the red lamp I have been using. I don't like the "on/off" type of thermostat I started with. Going to replace the foil covering the top with acrylic panels also, much easier to clean. One of these days I will get some pictures of all of this posted so I can get a full critique.
