Heat coils under substrate for planted aquariums?

[nekomi]

Hi,

I just read an article today that made mention of the use of heat coils in planted aquariums. I've never heard of anything like that before! Are they necessary? I'll be using a 29gal planted tank with 1/2 Flourite, 1/2 gravel with a thin sand layer on top.

If the heat coils are necessary, can I substitute a UTH (under-tank heater) similar to use in a reptile enclosure? It's basically a heating pad that sits under the glass.

Thanks for your help, I really appreciate it!!

nekomi,

The short version is no, undergravel heaters aren't necessary. However, take a look at this excellent article by Karen Randall for more thoughts and details.

Thanks for your quick reply! I just went and read the article. I guess reptile heating pads are out! Well, I may just add some foam insulation underneath like they recommended. Thanks again!

Many hobbyist have used substrate heaters effectively in both plant and Dwarf Cichlid tanks, but I agree with 2la. They are not necessary.
