Thanks Caryl
I have just talked to three different people, one of them being Stuart Lord, and all of them have said the same thing. the smartest, most cost effective way to go would be heating pads, as heat rises etc etc
( cant be bothered going into further detail as i have got myself worked up and stressed after being told, "bad" information about heating pads)
Stuart also, to my surprise said "do you know Caryl Simpson, she would be the person to talk to and alot more knowlagble than me on the subject"!!
One thing he did stress though was get a good thermometer that has a dial to control the temperature.
Looks like you certainly are popular Caryl
Every article i have read on heating pads suggests the above, that heating pads use slightly less power than aquarium water heaters, and even though are harder to find and cost more would be cheaper in the long run.
that was why i was so surprised as were the people i have talked to, when they were told some of the commments in regards to heating pads effecciacny.
MAN was i stressing!!
Cheers
