What size/how many UTH for:

[RagginOut]

What size and/or how many UTH's should I get for a 55gallon glass tank with a tile substrate?

Also, I understand that leo's do not bask, however if I had a heat lamp heating a river rock, would this serve as a 'hot rock' to aid in digestion or more hassle than it's worth?

thanks

oh, and what prices are fair priced for them as well. I understand I may need a rheostat as well to regulate the temperature of them?

Companys make UTH for your size tank so only 1 would be needed. Here is an example http://www.zoomed.com/db/products/E...iO3M6MToiMCI7czo4OiJTZWFyY2hfeSI7czoxOiIwIjt9

I am sure that exo terra makes an equivalent UTH.

No idea about price. Rheo stat is always a good idea especially during the summer months when its hot and the UTH might get too hot.
