when ordering heat tape from reptile basics....

do I put the length of each strip I want in the comment section if I am ordering them premade??

Also should i get 3" or 4" for 32ish qt tubs??? if 3" what voltage? 6 wpf? or 10 wpf?

If you are having them put it together for you, you can say how long you would like each strip to be or you can order like 3 feet and just cut it to length when you get it. I would go with the 4' for those tubs. What are you using to control the temps? Hope that helps you out!
