Does anyone, by chance use under tank heat pads on planted tanks? Not necessarily on a PDF tank; maybe a tropical lizard or hylid set up? My goal is to only warm the substrate just a bit in the winter for my aroids, cryptanthus and episcia. (E.g., + 5-10 deg, maybe mid-high 70s fahrenheit in a 68 deg room). If so:
1) How much can/do they actually heat the substrate (above room temp)?
For a 30 gallon tank, would 8W do it, or do I need 16W?
2) Are they always safe, even with a false bottom?
3) Any opinion on Zoo Med uth vs. Exo Terra "Rainforest?" (I have used the Zoo Med in the past; not bad, but they seem to only last a few years).
Opinions, guys?
