For those using U.T.H.'s which brand do you use/ recomend. I am looking for a rather large pad. I am in the prosses of setting up a rather good size tank for my B.P. I know alot of people out there think I probaly shouldn't use such a big tank but it WILL be nice and full of vegiatation water bowls and hides so I think he will feel safe and secure. However I am courious about the Ultratherm Heat Pads. Thank you. Ray
