Hi, can anyone help me on this? I have switched to slate as a substrate. the only prob is my slate tile is about a 1/2 " thick. i dont think the heat is getting through . the regular surface temp is ok becuz of the overhead, but im worried about the hide temps. they are significantly lower.
im using a cobra mat on a 20 gal flr space w/ temp cntrol.
(i have it cranked) any other UTH suggestions?
thanks
