Multiple things here. I'm moving from a 20 gallon (not long), to an Exo-Terra 36x18x18. I have the accompanying Compact Top light fixture and have 2 40W incandescents and one 26W CFL. Quite a big change for him. My current overall temp is 75-76 and I want it to be 85-90. First- Undertank heater, I have one that doesn't perma-attach but it's really a pain to apply. I also have a Zoo Med Repti-Therm UTH unopened and want opinions on brands and effectiveness of UTH. Second- Can I put one of my old incandescents (either 100W Night or 75W Day) in the remaining light socket to raise the temp? I hate to buy another CFL when I have two working lights. Third- I know I need a thermostat for at least the heat mat if not the lights. Also a timer because I'm going on vacation in a month for seven days. Brands and names, prices please? I'd like to not spend 100 bucks on one but it seems the proportional ones are about that. Is that necessary? I bought little rubber feet (technically rubber doorknob stoppers) to raise the bottom of the tank because my substrate is sand and I don't want to thermal block the UTH. Will that allow the heat to flow enough so I can have the sand thicker than 1/2 inch? Fourth- Where do people get all those awsm plants that look so real?! I can't find anything but those dinky little suction cup plants-in-bag stuff they sell at Petco. And last- Yes I know sand can cause impaction. I have the play sand washed and sifted which is the least-dangerous. They don't make reptile carpet in wonky in between sizes and he seems to love the sand even more. I have seen him lick it a couple times but both his poops since then have had minimal if none sand included. I'm very vigilant and watching for signs, it helps that I'm over-paranoid too What about that "Desert Sand" stuff? Is it really just desert sand, or another name for that dreaded Calci-Sand? Anymore details you need to know, just ask!
