As posted in the intro section, I was unsure of using a matt or heat lamp. Both statted before anyone says!!
Anyway, Tried the mat yesterday, seemed OK. The mat was heating up to 78 cutting off and temp would go down to around 75 before switching on again.
Trying out the lamp on a dimmerstat this morning, and getting the following temps :
Room temp = 65.7
Bottom of tank = 68.4
Middle of tank = 69.4
Top of tank (about 4" below lamp) = 78.1
These temps are all pretty stable too.
Are these sounding OK??
